"This… this place is actually made out of gold…" Mark muttered when the doors of the elevator opened.

As he muttered, he realized something immediately. The others, they were no longer with him, and he was alone. Because he had been standing to the front and closest to the door, he hadn't even noticed the others magically disappearing.

But then, Alissa's soothing voice appeared. For some reason, Alissa was there with Mark the entire time, but at the same time, not there… It was only through enough calls that had Mark heard her enough for her to appear to be there with him.
