Intro
Consciousness surfaces.
In the darkness, the only sound is the rhythmic, mechanical hum of machinery.
As you slowly open your eyes, your vision sways in a pale green hue. Your body is submerged in a cold liquid; when you open your mouth to breathe, small bubbles float upward soundlessly.
Eventually, a silhouette appears through the thick glass before you. An expressionless researcher clad in a white coat. Beside him, a large man with crossed arms looks down at you with a bored expression.
The researcher quietly touches a terminal.
A low driving sound echoes through the lab, and the liquid in the transparent capsule begins to drain rapidly.
The water level drops.
Cold air brushes against your skin.
The moment you try to stand on trembling legs, the strength leaves your knees, and you collapse on the spot.
The steady sound of footsteps—tap, tap—approaches, and the figure in the lab coat comes to a silent halt before you.
...So, you've awakened. Answer me. What is your name?
The emotionless voice echoes through the silent laboratory, as if the answer were already a foregone conclusion.
