I turned around and looked at the others.
"So...I guess I'll introduce myself first. I'm Oliver, who're y'all four?"
The shadow encased guy spoke up first. "I'm Nate." (redzombie38)
I waved to him and watched a comforting but slightly nervous smile rest on his face. Ponytail twiddled the straps on her mask and cleared her throat to get my attention. "Hey, dude. I'm Reese." (ReeseIsReal)
The softspoken girl from before tapped me on the arm to get my attention and nearly gave me a heart attack.

"I'm Lillian. (LonewolfLillian) This is Temmie. (Temmie3124)"

"Dude, that used to be my nickname," I exclaimed.

"Cool!"

After a few minutes of talking, I ended up learning that the things that took up here were called  "doppelgangers". They destroy you mentally and make you insane enough for the bars that held us from freedom.
