The summons arrived three weeks after Grimm's refusal of the faction invitations.
Not an invitation this time, but a command—delivered by a creature that existed only in the peripheral vision, visible when not looked at directly. It left a mark on his chamber door: a spiral of darkness that absorbed the torchlight around it, pulsing with the rhythm of a heartbeat that wasn't his own. The mark seemed to breathe, expanding and contracting with a slow, deliberate rhythm that made the air itself feel heavy.
The Netherheart requests your presence. Midnight. The Threshold.
Grimm studied the mark with his Pre-Saint perception, peeling back layers of magical encryption that shifted like oil on water. Beneath the surface, he found structure—an intricate network of connections, each node representing a location within the Holy Tower, each line representing... influence. The mark wasn't merely a message. It was a map. A glimpse into something vast and hidden, a fragment of a pattern that extended far beyond what he could immediately comprehend.
He traced one line with his consciousness, following it through the Tower's architecture, through walls and wards and the spaces between spaces. It terminated at the Dimensional Faction's archives. Another led to the Combat Faction's armory. A third wound its way to the private chambers of the Tower's High Council itself. Each connection glowed with a different hue—some silver, some gold, some colors that had no names in any language he knew.
Nethros's network. The Soul Web.
The Threshold existed in a part of the Holy Tower that Grimm had never visited—a zone where the Tower's geometry became unstable, where corridors looped back on themselves and staircases led to places that shouldn't exist. The air here tasted of copper and absence, the metallic tang of blood mixed with the hollow emptiness of the void. It coated his tongue like a film, making every breath feel like inhaling the memory of something that had once been alive.
Nethros waited in a chamber that seemed carved from shadow itself. Not darkness—darkness implied the absence of light. This was something else, something that consumed light, that devoured illumination and left only the suggestion of form. The space seemed to breathe around him, walls expanding and contracting in a rhythm that matched the mark on his door.
"You studied the mark," Nethros said. It wasn't a question.
"It showed me your network."
"It showed you a network." Nethros's form shifted, the shadows composing him flowing like liquid mercury. "What you saw was a fraction. A single thread in a tapestry that spans centuries. There are layers upon layers, Pre-Saint. Connections within connections. Patterns that only become visible when you know how to look."
Grimm said nothing, waiting. He had learned that Nethros's revelations came in their own time, that pushing for information only delayed its arrival.
"You wonder why I reveal this to you." Nethros gestured, and the chamber's walls became transparent—not to the outside world, but to something else. Grimm saw connections, thousands of them, glowing lines of force that webbed through the Holy Tower like the neural pathways of a vast organism. The sight was overwhelming, a three-dimensional maze of light and shadow that seemed to pulse with the life force of the Tower itself. "You refused the factions. Chose independence over security. The price of that choice is isolation—or it would be, without alternative resources."
"You're offering me access to your network."
"I'm offering you knowledge of its existence." Nethros moved closer, and Grimm felt the temperature drop—not physically, but in the space between them, the temperature of the soul. It was like standing at the edge of a precipice, feeling the pull of the void below. "The Soul Web has existed since the Second Age, when the first Netherheart bound the void to wizardly purpose. It predates the Holy Tower. Predates the current civilization. It has survived wars, cataclysms, the rise and fall of empires."
Grimm studied the web of connections, cataloging patterns. The lines weren't random—they followed rules he couldn't yet understand, clustering around certain points while avoiding others. "How many nodes?"
"Currently? Nearly five thousand active agents. Twice that number of informants. A quarter of the Tower's population, directly or indirectly." Nethros's voice carried something that might have been pride, or perhaps something more complex—satisfaction mixed with weariness. "The Elemental Faction believes they control fire. The Combat Faction believes they control force. The Knowledge Faction believes they control information. They are all wrong. I control the spaces between. The whispers in the dark. The secrets that burn in the silence."
"And what do you want in exchange for this knowledge?"
Nethros's form rippled—amusement, perhaps. Or something more calculating. "For now? Nothing. Consider it... a demonstration of value. The first lesson in a curriculum I have been planning since the day we met."
Grimm felt the weight of that statement. Since the day they met. Years ago, when he had first arrived at the Holy Tower as a raw hunter seeking advancement. Nethros had been watching him, planning for him, cultivating him like a gardener tending a particularly promising seedling.
The history lesson began as they walked through corridors that shouldn't exist.
"The Nether Faction is not like the others," Nethros explained, his voice echoing from directions that didn't match his apparent location. The sound seemed to come from everywhere and nowhere, creating a disorienting effect that made Grimm's sense of direction spin. "They seek power through elemental mastery, through combat prowess, through alchemical transformation. We seek power through understanding the fundamental nature of existence itself."
They passed through a doorway that opened onto a vista of stars—not the stars of any sky, but the cold pinpricks of light that existed in the void between dimensions. Grimm recognized them: the dimensional substrate, viewed from within the Tower's protected space. The sight was both beautiful and terrifying, an infinite expanse of darkness punctuated by distant lights that might be worlds, or might be something else entirely.
"The Nether Realm," Nethros continued, "exists at the boundary between life and death, matter and void, existence and non-existence. It is not a place in the conventional sense. It is a state. A condition. The space where souls go when they are not quite dead and not quite alive."
"You rule there."
"I am there." Nethros turned, and for a moment Grimm saw something beyond the shadows—a vast expanse of floating islands, each one a repository of souls, connected by bridges of pure consciousness. The islands glowed with soft, ethereal light, and Grimm could sense the weight of countless souls pressing against his perception like a physical force. "The title of Netherheart is not inherited. It is earned through transformation. Through becoming something that can exist in that space without being consumed by it."
They entered a chamber filled with artifacts—objects that hurt to look at directly, that seemed to exist in multiple states simultaneously. Weapons forged from crystallized screams. Armor woven from the memories of the dead. Tomes written in languages that had never been spoken by living tongues. The air here was thick with history, with the accumulated weight of centuries of study and sacrifice.
"The Nether Faction's power," Nethros said, gesturing to the collection, "comes from our ability to interact with what others fear. The void. Death. The dissolution of self. While other factions build walls against these forces, we study them. Befriend them. Make them our tools."
Grimm approached a display case containing what appeared to be a spider web—except the strands were silver, and they moved, and each intersection held a tiny point of light. The web seemed to sing, a sound just below the threshold of hearing that made his teeth ache. "What is this?"
"The original Soul Web." Nethros stood beside him, and Grimm felt the weight of centuries in his presence. "Created by the first Netherheart three thousand years ago. Each intersection is a soul. Each strand is a connection—love, hate, obligation, debt. The web shows how all lives are intertwined, how no existence is truly isolated."
"And you use this to..."
"To understand. To predict. To influence." Nethros's void-eyes reflected the web's silver light. "When you know how souls are connected, you know where to apply pressure. Who to approach. What leverage to use. The Soul Web is not merely an intelligence network, Pre-Saint. It is a map of causality itself."
Grimm studied the web, seeing patterns emerge. He recognized some of the lights—faint impressions of souls he had encountered. Millie's glow was there—the young apprentice he had mentored in his early years at the Tower—connected to his own by a strand that pulsed with complex emotion. Mina's light burned brighter, golden and fierce, the researcher from the Knowledge Faction who had assisted him in the Dimensional Archives, connected to something larger than individual relationships. The realization was humbling: his life, his connections, his very existence was part of this vast pattern, visible to Nethros in ways he could barely comprehend.
"You see yourself," Nethros observed. "And those connected to you."
"How many know of this?"
"Of the web's existence? A few dozen. Of its full extent?" Nethros's form shifted, and Grimm felt the weight of his attention. "Three. Including you."
They sat in a space that existed outside normal geometry—a room with seven corners, three of which were visible only from certain angles, one of which could be entered but never exited. The furniture seemed to shift when not observed, chairs becoming tables, tables becoming something that might have been alive.
"You wonder about my motives," Nethros said. It wasn't a question.
"You show me secrets that could destabilize the Holy Tower. Reveal networks that took centuries to build. Share knowledge that others would kill for." Grimm kept his voice neutral, his absolute rationality engaged. "There are three possible explanations. One: you seek to recruit me into your faction, and this is the price of admission. Two: you need something from me that requires my understanding of your capabilities. Three: you are preparing me for a role I do not yet comprehend."
"And which do you believe?"
"All three. In different proportions."
Nethros's laughter was like wind through hollow bones. "Precisely. You understand the complexity of our relationship better than most understand simple friendship." The sound echoed strangely in the impossible room, seeming to come from multiple directions at once.
"Is that what this is? Friendship?"
"What is friendship but mutual benefit wrapped in emotional packaging?" Nethros gestured, and the air between them filled with images—moments from their history together. Grimm's first arrival at the Holy Tower. Their initial meeting. The training sessions. The missions. The quiet conversations in spaces like this one. Each image glowed with a soft light, suspended in the air like fireflies frozen in time. "I have invested in you, Pre-Saint. Time. Knowledge. Resources. Political capital. These investments create obligation—not legal obligation, but the weight of reciprocity."
"And what return do you expect?"
"That is the question, isn't it?" Nethros leaned forward, and Grimm felt the pressure of his attention like a physical force. "I could tell you that I expect loyalty. That I expect service. That I expect you to become my weapon, my heir, my successor. All of these would be partially true. All would be incomplete."
"Then tell me the complete truth."
"The complete truth is that I do not yet know what you will become." Nethros's voice dropped to a whisper that seemed to come from everywhere at once. "I have plans, yes. Visions of possibility. But you are... unpredictable. The dimensional affinity makes you so. You exist partially outside the web, partially outside the patterns that govern other souls. This makes you valuable. And dangerous."
"To you?"
"To everyone. Including yourself." Nethros rose, moving to the window that looked out on the void between dimensions. The view shifted as he approached, showing different angles of the infinite darkness. "Do you know why I chose to mentor you? Not the official reason—the unofficial one."
"Tell me."
"Because you reminded me of myself." The admission seemed to cost something, a fragment of the mask slipping away. "Not the you that exists now—the you that existed before. The hunter who chose transformation over humanity. Who saw the path to power and walked it without looking back."
Grimm considered this. "You regret your transformation."
"I regret nothing. I observe that transformation has costs. That the path I walked left me... diminished. In ways I did not anticipate." Nethros turned back to face him. "You have made the same choice. The Mutation Domain. The dimensional studies. The systematic replacement of human limitation with something else. I recognize the pattern because I lived it."
"And you want to prevent me from making your mistakes?"
"I want to see if you can avoid them. If the dimensional affinity provides something that the void could not. If your path leads somewhere mine could not reach." Nethros's form rippled with emotion—anticipation, perhaps. Or hunger. "This is the complexity of our relationship, Pre-Saint. I am your mentor, yes. Your ally, yes. But I am also your observer. Your experimenter. The one who watches to see what happens when certain variables are introduced."
"You experiment on me."
"I cultivate you. There is a difference." Nethros returned to his seat, the moment of vulnerability passing like a cloud before the sun. "An experiment implies control. Cultivation implies... partnership. Mutual investment in an uncertain outcome."
Grimm studied his mentor, seeing him with new eyes. The void-eyes that revealed nothing. The form that was never quite solid. The power that radiated from him like heat from a furnace. This was not a simple relationship. It was not friendship, nor was it purely transactional. It was something else entirely—a complex web of mutual interest, shared history, and uncertain future.
The revelation came without warning, as Nethros's most important revelations always did.
"The Dimensional Faction and the Nether Faction," he said, as if discussing the weather, "were once a single entity."
Grimm stored the information, waiting for context. He had learned not to react immediately to Nethros's statements, to let them settle before responding.
"In the First Age, before the current civilization, there existed an order called the Threshold Walkers. They studied the boundaries between states—between dimensions, between life and death, between existence and void. They believed these boundaries were not separate domains but aspects of a single underlying reality."
"What happened to them?"
"They fractured." Nethros gestured, and the air filled with historical images—wizards in robes of silver and black, gathered around dimensional rifts, studying the void. The images moved like living memories, showing scenes of research and discovery, of heated debates and growing divisions. "A schism over methodology. Those who believed in direct experimentation with dimensional forces became the ancestors of the Dimensional Faction. Those who believed in studying the void through its interaction with souls became the ancestors of the Nether Faction."
"They split over philosophy."
"They split over fear." Nethros's voice carried the weight of ancient history. "The Threshold Walkers discovered something. Something that terrified them so profoundly that they chose to destroy their own order rather than continue the research. The two factions that emerged were born from that terror—from different responses to the same revelation."
Grimm felt the importance of this information settling into his strategic awareness. "What did they discover?"
"That the dimensional substrate and the Nether Realm are not separate. That they are the same space, viewed from different perspectives. That the void between dimensions is also the void between life and death. That dimensional travel and soul travel are aspects of the same underlying phenomenon."
The implications unfolded in Grimm's mind like a flower blooming. "The dimensional affinity and the Nether abilities..."
"Are fundamentally connected. Yes." Nethros nodded, the gesture surprisingly human. "This is why the Dimensional Faction wants you so desperately. Not merely because you have dimensional affinity, but because your Mutation Domain—your ability to transform your own biology—represents a bridge between their approach and ours."
"And this is why you want me."
"Precisely." Nethros's form shifted, the shadows composing him flowing with what might have been excitement. "For three thousand years, the two factions have pursued their separate paths, each believing they held part of the truth. But the complete truth requires both. Requires someone who can exist in both spaces. Someone who can walk the Threshold in both directions."
"Someone like me."
"Someone exactly like you." Nethros leaned forward, and Grimm felt the intensity of his focus. "The Dimensional Faction knows this. They have known since you first demonstrated your Mutation Domain. They want to claim you, to shape you into their tool for rediscovering the Threshold Walkers' secrets."
"And you?"
"I want to help you discover those secrets for yourself." Nethros's voice dropped to a whisper. "Not as anyone's tool. Not as anyone's weapon. But as something new. Something that has not existed since the First Age. A true Threshold Walker."
The words settled into the silence between them, carrying the weight of three thousand years of divided knowledge.
The chamber's geometry shifted, the seven corners becoming nine, then twelve, then a number that Grimm's perception refused to count. The walls seemed to breathe, expanding and contracting in a rhythm that matched his own heartbeat.
"You have shown me your network," Grimm said. "Your history. Your connection to the Dimensional Faction. But you have not shown me your purpose. Why cultivate me? Why reveal these secrets? What do you actually want?"
Nethros was silent for a long moment. When he spoke, his voice carried the weight of centuries. "I want to complete what the Threshold Walkers began. To rediscover what they feared. To understand the true nature of the boundary between existence and void."
"And you need me for this."
"I need someone who can go where I cannot." Nethros rose, moving to the window that looked out on the void. The view shifted as he approached, showing different angles of the infinite darkness, different perspectives on the nothingness between worlds. "I exist in the Nether Realm. I can touch the dimensional substrate. But I cannot fully enter it. My transformation—the one that made me Netherheart—binds me to the void between souls. I cannot cross into the space between dimensions."
"But I can."
"You can. And more importantly, you can return." Nethros turned back to face him. "The Threshold Walkers' greatest secret was not merely that the two realms are connected. It was that there exists a space beyond both. A place where dimension and void merge. Where the fundamental rules of existence themselves become... negotiable."
"And you want me to find this place."
"I want you to reach it. To see it. To understand it." Nethros's form rippled with intensity. "And then to return and tell me what you found."
Grimm considered this. "Why? What value does this knowledge have?"
"Immortality." The word hung in the chamber like a physical presence, seeming to make the geometry shudder. "True immortality. Not the extended lifespan of a Saint. Not the persistence of a soul in the Nether Realm. But existence unbound by time itself. The Threshold Walkers believed that in the space beyond dimension and void, the rules that govern mortality do not apply."
"You want to live forever."
"I want to continue." Nethros's voice carried an edge of desperation that Grimm had never heard before. "I have lived for eight centuries, Pre-Saint—far beyond the natural span of a Rank 6 Saint, sustained only by the Netherheart transformation that now consumes what remains of my soul. I have seen civilizations rise and fall. I have accumulated power beyond the dreams of most wizards. But I am dying. Not physically—my form is stable. But my soul is... fraying. The transformation that made me Netherheart consumes what I was. Every century, I lose more of my original self. In another two hundred years, there will be nothing left but the void."
"And you believe this space beyond can save you."
"I believe it can transform me. Again. Into something that does not decay. That does not dissolve into the nothingness it studies." Nethros moved closer, and Grimm felt the weight of his hope like a physical pressure. "This is my true purpose, Pre-Saint. This is why I cultivate you. Why I reveal my secrets. Why I prepare you for what comes next."
"And what comes next?"
"Your ascension." Nethros's voice dropped to a whisper that seemed to come from everywhere at once. "When you achieve Saint-level, you will be able to go further into the dimensional substrate than any living wizard. You will be able to reach the Threshold—the true Threshold, not the metaphor. The place where all boundaries dissolve."
"And then?"
"And then you will help me complete my work." Nethros extended a hand composed of shadows. "Not as my servant. Not as my tool. But as my partner. The one who can go where I cannot. Who can see what I cannot see. Who can bring back the knowledge that will save what remains of my soul."
The offer hovered between them, heavy with centuries of planning and hope.
Grimm did not take the offered hand.
Instead, he studied Nethros with his absolute rationality, weighing the revelation against everything he knew. The desperation in Nethros's voice. The specificity of his request. The centuries of investment that this moment represented. The shadows that composed his mentor's form seemed to shift and flow, as if reflecting the uncertainty of the moment.
"You ask me to trust you," Grimm said. "To believe that your purpose is as you describe. That your cultivation of me is partnership rather than exploitation."
"I ask you to consider the evidence." Nethros lowered his hand, the shadows composing it flowing back into his form. "The consistency of my actions over years. The resources I have invested. The secrets I have revealed. These are not the actions of one who seeks to deceive."
"Or they are the actions of one who understands that apparent vulnerability creates trust."
Nethros's laughter was like wind through hollow bones. "Precisely. You learn well." He moved back to his seat, the intensity of the moment passing. "So. What is your assessment? Am I the desperate seeker I claim to be? Or am I playing a deeper game?"
"Both." Grimm's answer was immediate. "You are desperate. The fraying of your soul is real—I can see it in the instability of your form. But you are also playing a game. The revelation of your purpose serves your interests, even if the purpose itself is genuine."
"And what interests might those be?"
"Binding me to you. Creating obligation. Making me complicit in your secrets so that I cannot easily betray them." Grimm's voice remained neutral, analytical. "These are not necessarily hostile actions. They are the actions of one who has survived for centuries by being careful. By creating mutual dependencies. By ensuring that those he needs have reasons to need him in return."
Nethros was silent for a moment. Then: "You understand me better than I expected."
"I understand the logic of survival." Grimm rose, moving to the window that looked out on the void. The view was hypnotic, an infinite expanse of darkness that seemed to pulse with its own rhythm. "You want my help. You believe I can reach this Threshold, this space beyond dimension and void. You are probably correct—I can feel the potential in my dimensional affinity, the sense that there are depths I have not yet explored."
"And?"
"And I will consider your proposal." Grimm turned back to face his mentor. "Not because I trust you. Not because I accept your narrative of partnership. But because your goal and mine may align. I too seek to understand the dimensional substrate. To explore its depths. To discover what lies beyond the boundaries of conventional existence."
"You seek power."
"I seek knowledge. Power is a side effect." Grimm's voice carried the absolute certainty of his rationality. "If helping you reach this Threshold advances my own understanding, then cooperation serves both our interests. If it does not..."
"Then you will walk your own path." Nethros nodded, the gesture carrying something that might have been respect. "I would expect nothing less. You are not a tool to be used, Pre-Saint. You are a force to be navigated. I have always known this."
"Then we understand each other."
"We understand each other." Nethros rose, and the chamber's geometry shifted back to something more conventional. "The web is yours to use, when you need it. The knowledge is yours to explore. And when you are ready—when you have achieved Saint-level and can survive the deep substrate—we will discuss the Threshold again."
Grimm nodded, turning toward the exit. At the doorway, he paused. "One question."
"Ask."
"The other two who know the full extent of the Soul Web. Who are they?"
Nethros's form rippled—amusement, perhaps. Or something more cryptic. "One is the Dimensional Faction's leader. The other... you will meet in time. When you are ready."
Grimm filed the information away and stepped through the doorway, back into the corridors of the Holy Tower. Behind him, the shadows whispered secrets he was not yet prepared to hear. The weight of what he had learned pressed against his consciousness like a physical force—the web, the Threshold, the desperate hope of an ancient wizard seeking immortality.
He walked through the unstable corridors, his mind processing everything. The Soul Web. The Threshold Walkers. The space beyond dimension and void. Nethros's true purpose. Each piece of information shifted his understanding of his position, of his path forward, of the complex web of relationships that defined his existence in the Holy Tower.
The factions had sought to claim him. Nethros sought to partner with him. But Grimm knew, with the certainty of his absolute rationality, that he would remain what he had always been: independent. Not alone, but choosing. Always choosing.
The corridor ahead twisted in impossible ways, but Grimm walked forward without hesitation. He had his own path to walk, his own destiny to forge. And when the time came to face the Threshold, he would do so on his own terms—not as Nethros's tool, not as anyone's weapon, but as himself.
The thought brought a strange comfort. In a world of webs and schemes, of hidden purposes and desperate hopes, there was power in simply being oneself. In choosing one's own path. In refusing to be defined by the expectations of others.
Grimm smiled—a rare expression that felt foreign on his face. The game was complex, the stakes were high, and the players were ancient and powerful. But he was Grimm. The hunter who had survived the death of his humanity. The Pre-Saint who walked between dimensions. The force that could not be owned, only navigated.
Let them scheme. Let them plot. Let them weave their webs of influence and obligation.
He would walk his own path.
And when the time came, he would face the Threshold not as a supplicant, but as a conqueror.
