The transition from the High Tower to the sub-basement wasn't just a descent in altitude; it was a shift in reality. Up there, the world was built on the vibration of mana—noisy, bright, and suffocating. Down here, behind the rotted oak doors of the Old Library, the world was silent.
I sat cross-legged on the cold stone floor of the hidden chamber. Around me, the massive glass tanks hummed with a low, rhythmic thrum, the liquid inside dark as ink. The Guardian stood in the corner, his presence less like a person and more like a tear in the fabric of the room.
"You have three days," the Guardian's voice echoed, rasping like dry parchment. "The Voss Clan brings the Eye of Truth. It is a divine artifact that projects the internal landscape of the soul onto a scrying mirror. If they look at you now, they will see a void. And a void is an admission of guilt."
"Then teach me how to build a lie," I said, my voice steady.
"It is called Void-Skin," the Guardian said, stepping into the dim light. "You cannot create mana, boy. You are a Null. But you can shape the nothingness. You must learn to pull the Void-Core's energy to the surface of your skin and freeze it into the shape of broken veins."
I closed my eyes and reached inward.
In the center of my chest, the Void-Core—that swirling, hungry singularity I had carried since birth—pulsed. Usually, I kept it tightly wrapped in layers of mental suppression. Now, I began to uncoil it.
Step 1: The Extraction. I reached into the core and pulled a thread of "Nothingness" upward. It felt like freezing mercury sliding through my chest.
Step 2: The Mapping. I visualized the Valerius family bloodline—the silver, flowing rivers of mana that Elara possessed. I mapped those exact paths onto my own arms, but I imagined them shattered, blocked, and burnt.
Step 3: The Condensation. I forced the void-energy to the surface of my skin.
"Argh—" I gasped, my back arching.
The sensation was agonizing. It wasn't like a physical burn; it was the sensation of my skin being erased and replaced with a static image. I looked down at my forearms. Faint, dark lines began to trace their way under my skin. They looked like bruised veins, but instead of blood, they were filled with a flickering, shadowy smoke.
"Focus," the Guardian commanded. "The Eye of Truth will look for 'Mana-Burn.' If the lines are too steady, they will know it is a mask. You must make them look like the result of a failure."
I gritted my teeth, sweat pouring down my face. I manipulated the void threads, snapping them in certain places, making the "veins" look like they had exploded from the inside. I was literally sculpting a tragedy onto my own flesh.
A soft knock echoed at the top of the stairs. I quickly pulled my sleeves down, the Void-Skin stinging as it settled into my pores.
Lyra descended the stairs, her face pale. She was holding a small, crystal vial filled with a sickly, yellowish liquid.
"I got it," she whispered, her hands trembling. "The Fragility Draught. It's used by failed mages who want to sue their masters for 'over-training.' It temporarily thins the blood vessels and makes the skin as sensitive as a bruise."
"Give it here," I said.
"Cassian, wait," Lyra grabbed my wrist. "If you take this and then use the Void-Skin, the reaction could be permanent. You're playing with the chemistry of your body. If you miscalculate, you won't be faking a heart condition—you'll actually have one."
I looked at the vial, then back at the stairs that led up to the world of the S-Ranks.
"Elara is already suspicious," I said. "And Kaelen's father doesn't believe in coincidences. If I show up to that appraisal looking healthy, I'm dead. If I show up looking like a dying 'Dud' who tried too hard to be a hero, they'll laugh and let me live. I'll take the risk."
I uncorked the vial and swallowed the bitter liquid in one go.
The effect was instantaneous. My heart began to flutter like a trapped bird. My skin turned a sickly, translucent white, and the dark Void-Skin lines beneath my surface began to throb with a dull, purple ache. I looked into a shard of broken mirror on the floor.
I looked like a corpse that had been brought back to life by a bad spell. I looked... perfect.
"Now," I said, my voice weak and raspy—a side effect of the draught. "The Combat Trial. I need to practice the fall."
"Cassian, you can barely stand," Lyra said, catching me as I stumbled.
"That's the point," I whispered. "If Kaelen Voss hits me with a lightning bolt in the arena, my Void-Skin needs to 'shatter' in a way that looks like a mana-backfire. I need to learn the timing. If I erase his spell too early, it looks like a Null-shield. If I erase it too late, I actually die."
For the next four hours, in the damp darkness of the basement, I practiced the most difficult move of my life: The Perfect Defeat.
I would lunge at an imaginary opponent, then purposely "trip" my own internal energy, causing the Void-Skin to flare and then go dark. I practiced the exact way my body should hit the dirt, the exact way my breath should hitch, and the exact moment my eyes should roll back.
"You're becoming a monster of a different kind, boy," the Guardian watched from the shadows. "Most men train to survive. You are training to be broken."
"In this Academy," I said, coughing up a small fleck of dark, void-tinted blood, "being broken is the only way to be invisible."
As the first light of dawn began to creep through the cracks in the basement ceiling, I stood up, leaning heavily on a bookshelf. My body was in ruins, my heart was skipping beats, and every inch of my skin felt like it was being pricked by needles.
I looked like a tragedy. I looked like a failure.
I was ready to meet my sister and the High Priest.
