Aisam pushed the key toward the wall as the tip of the key went in, and it looked like the small area of the wall that the key was pushed into turned into liquid.
A black gate, its surfaces streaked with a blood-red hue resembling pulsating veins, emitted soft, rhythmic sounds akin to a heartbeat. Surrounding it was a dark, ominous purple aura as it appeared in front of him, emerging from the wall a meter higher than his height of C-01 (currently + original's hair and eyes color; will be called 'Regular' from now on) as the top of the gate hit the ceiling of ice walls.
The gate seemed like a steel door but not due to its sturdy and structured format, and instead made of an unknown material.

He fell silent for a few moments as he stared at the gate.
'It is almost... like I imagined.'
"Come here, and follow me," he ordered Celia as she came forward and stood behind him.
He pressed his hands on the gate trying to open it.
