What was that?
Outside the sheet-like structure containing the C'tan shard.
Someone had already approached the substance.
The thing, like a film of water, remained still.
A Chaos mechanical arm was attempting to touch the substance.
Yet when its arm made contact with the substance, it suddenly sensed something was wrong, as though it had activated the inert object.
As if it had flesh, it coiled around its arm.
The sensation was like threads at the atomic level passing straight through its body. Its body suffered no damage, yet it could clearly feel something piercing through it from within.
"It's that thing!"
"What is that thing?" The people seated inside the cabin were also curious about what they had come into contact with.
Very soon.
They sensed that something was wrong. The Warp, which had already been torn open.
Suddenly seemed to have formed some kind of barrier again. An incomprehensible wall of the material universe isolated their psychic power outside, and they needed tremendous effort to wield their psychic abilities.
"Damn it, what the hell is this?"
While they were still panicking over what the thing was.
The power of the C'tan shard drove the containment membrane to expand into the rift torn open in the Warp at a speed imperceptible to the naked eye.
The C'tan's power naturally merged with the laws of the material universe and surged toward the intact regions of reality. That thin membrane replaced the barrier between the material universe and the Warp. As the C'tan merged with reality, it continuously generated more membrane, expanding the area it covered. Its expansion speed was actually the speed of light, healing the cracks torn open by the Warp at light speed.
