Rin stared at the masked figure, his heart pounding. "You were a student here? Fifteen years ago?"
"Top of my class. Platinum rank two. Destined for greatness." Shade's voice carried bitter amusement. "Then I made the same mistake you did. I opened a door that should have stayed closed."
"You summoned something from the Nexus."
"Not something. Someone." Shade moved closer, his movements unnaturally fluid. "A legendary assassin who existed between life and death. The bond changed me, just like yours is changing you. But I didn't have anyone to warn me, no professors researching solutions. I had to figure it out alone."
"Then you know how to stop the corruption?"
"Stop it? No." Shade's laugh was hollow. "But I learned how to live with it. How to control it instead of letting it control you." He extended his hand, and shadows coalesced into a small black book. "Fifteen years of research, experimentation, and suffering. Everything I learned about Nexus bonds is in here."
Rin reached for the book, but Shade pulled it back.
"Nothing is free, Rin Eldraven. Especially not knowledge that could save your life."
"What do you want?"
"Three things." Shade held up a finger. "First, I want access to your summoning technique. The ritual you used to reach the Nexus. I've tried to recreate it for years and failed. You did it accidentally, which means your method is different from mine."
"I don't even know what I did differently."
"Then we'll figure it out together. Second..." Another finger. "When you inevitably summon more entities from the Nexus, and you will, I want to observe. Study the process. Document the bonds."
"What makes you think I'll summon more?"
"Because one Nexus bond marks you. The Nexus recognizes you now. Other entities will be drawn to you, will try to form contracts. It's inevitable." Shade's tone darkened. "I learned that the hard way."
Rin processed this. "What's the third thing?"
"When the time comes, and you'll know when it does, I need you to help me with something. I won't tell you what yet, because if I did, you'd refuse. But when I call in this favor, you'll understand why it matters."
"That's a terrible deal. You're asking me to agree to something without knowing what it is."
"Yes. But I'm also offering you the only real chance at survival you have." Shade gestured toward the academy below. "Those professors searching the archives tomorrow? They'll find my old notes, sanitized and incomplete. The headmaster made sure anything truly useful was removed or encrypted. He doesn't want another student like me."
"How do I know you're telling the truth?"
"You don't." Shade tossed the book, and Rin caught it reflexively. "Take it. Read the first chapter. If you think I'm lying, burn it and forget this meeting. But if you recognize the truth in those pages..." He produced a blank contract scroll. "Sign this, and I'll teach you everything I know."
Rin opened the book. The first page contained a detailed diagram of corruption marks, showing their progression across a human body. The patterns matched his own exactly. The next pages described symptoms: increased aggression, difficulty distinguishing self from summon, nightmares of the Nexus, physical changes beyond the marks.
Every single symptom matched what Rin had experienced.
"You felt it too," Rin whispered. "The pull toward the Nexus. Like something there is calling you."
"Every night." Shade's voice dropped. "The Nexus wants its legends back, Rin. Or perhaps it wants to collect new ones. Either way, we're connected to it now. Fighting that connection will destroy you. Learning to use it might save you."
Rin looked at the contract scroll. "What exactly would I be agreeing to?"
"A partnership. I teach you control techniques, provide research data, and help you survive your bond. In exchange, you share your summoning method, let me observe future summonings, and owe me one significant favor." Shade tilted his head. "Clock's ticking. You have a match tomorrow. How much corruption do you think you can handle before you lose yourself?"
"Why are you really helping me? What do you get out of this besides research data?"
Silence stretched between them. When Shade finally spoke, his voice was quieter, almost vulnerable.
"Because fifteen years ago, I was alone and desperate. I made choices that cost me everything. My position, my future, even my physical form." He held up his hand, and Rin saw it was translucent, barely solid. "I'm fading, Rin. Becoming more shadow than man. If I can help you avoid my fate, maybe that means something. Maybe it gives my mistakes purpose."
"That's not the whole truth."
"No. It's not." Shade's mask seemed to stare directly into Rin's soul. "The whole truth is that I think you're going to do something extraordinary. Something that might change everything we know about summoning, about the Nexus, about the boundaries between dimensions. And I want to be part of that. Call it academic curiosity or desperate hope, but I believe you're special, Rin Eldraven."
Rin held the contract scroll, weighing his options. Trust a mysterious stranger with unclear motives, or rely on professors who might not have complete information. Both paths were risky.
"If I sign this and you betray me..."
"Then you'll have a demon lord to sick on me. I'm not suicidal." Shade produced a pen that wrote in silver ink. "But I understand if you need time to decide. Keep the book. Read it tonight. Tomorrow, after your match, if you want my help, activate the crystal again. If not, we never speak again."
He moved toward the tower's edge.
"Wait," Rin called. "What happened to your summon? The assassin from the Nexus?"
Shade paused. "He's still here. Part of me now. We've merged so completely that I can't tell where I end and he begins anymore." He stepped off the edge, falling into darkness. His voice echoed back up. "Don't let that happen to you and Malachar. Some partnerships become prisons."
Then he was gone, leaving Rin alone in the bell tower with a book of forbidden knowledge and an impossible choice.
Rin descended the stairs slowly, clutching the book. Back in the medical wing, he pretended to be asleep when the night nurse checked on him. Once alone, he opened the book again and began reading by moonlight.
The techniques described were unlike anything taught at the academy. Mental exercises to separate self from summon. Meditation methods to slow corruption spread. Even combat strategies that used the corruption as a weapon rather than fighting against it.
But what caught Rin's attention most was a passage near the end of the first chapter:
"The Nexus is not a prison. It is a chrysalis. Defeated legends are not being punished. They are being transformed, prepared for something. What that something is, I have not yet discovered. But I believe the answer lies in understanding why certain summoners can access the Nexus while others cannot. We are not random. We were chosen. The question is: by what, and for what purpose?"
Rin closed the book, his mind racing. Chosen? For what purpose?
"The boy makes interesting points," Malachar said quietly. "In the Nexus, we didn't simply exist. We were... waiting. I never understood what for. Perhaps this Shade has insights I lack."
"You think I should accept his offer?"
"I think you should survive. How you accomplish that is your choice. But know this: the academy will never truly help you. You represent something they fear, something outside their control. This Shade, for all his mysteries, at least understands what you're going through."
Rin hid the book under his mattress as dawn light crept through the windows. In a few hours, he'd fight in the quarterfinals. After that, he'd make his decision about Shade's offer.
But deep down, he already knew what he would choose.
Survival demanded compromise. And he was running out of time.
