"Why is there a black hole outside?!" Ace screamed into the empty classroom, 'xcept for Apeiron of course.

"Calm down, You asked me to do this, didn't you? this is the ritual used to destroy the bridge." Apeiron replied calmly, with teasing smile on his face.

"Yeah, but I didn't tell you to spawn a fricking black hole in the sky!"

"Well you asked for one with the least consequences and you've got it. As long as you follow my lead exactly, the bridge will collapse and we'll get out of here with no damage."

Ace looked into Apeiron eyes with a skeptic gaze, he didn't trust Apeiron and he didn't bother hiding it.

After a while of staring at him, Ace relented.

"Well ~sigh~ I guess I get what I asked for… But what you said is stuff too vague, how does the black hole in the sky relate to the destruction of the bridge?"

Ace asked Apeiron not really because he wanted to know the details of the collapse of the bridge — Even if he did he wouldn't believe any information that came out of Apeiron's mouth — The real reason he asked was to observe his reaction and how much time he took to respond, so as to see if he was being dishonest with him.

Apeiron replied,

"The black hole in the sky is a bridge to the spiritual dimension; A metaphysical place between fiction and reality."

"Why did you open a bridge to this so called spiritual dimension?"

"To understand why I did that you would first have to understand what this place really is.

This place is a derivative space constructed on the link between our souls and made out of both our memories, what the bridge to the spiritual dimension does is to swallow up all the memories that construct this space, so we can see the link between our souls without anything superficial blocking it."
