"Alright, on with it," I replied, crossing my arms with my eyes never leaving the glitching black mass behind him.

"Rule number one: You always stay on the path. I dunno, some pretty weird stuff happens outside of the path, and I ain't about to go and check it out."
"Rule two: Don't stay longer than a few hours. A person will start to forget things... important things... like my 10th birthday."
"Rule trés: Close the portals you open when you leave. Notice those... you called 'em 'glitches', right? Yeah, that's what happens if you don't close them. Sorry about that... I'm in a rush and I don't always close them like I should... yeah, the void will escape. That's why I don't open a bunch at the same time, because I-"

"The void?" I replied.
"Well," he chuckled shyly, "that's what I call it. Or the goop, the black mirror, space and time, the hole... why, you got a name for it?"

I stared long and hard into the blackness.

"Nothing in particular."
