A Quick Count, Huge Profits

It was as if this Astral Plane was the universe, but this wasn't the universe that Roland perceived in his real-world view.

At least there wouldn't be so many bugs floating around in the universe, or some quirky fragment of life, or a slice of time, or incomprehensible and completely unintelligible ramblings and mumblings.

"Everything in the Astral Plane is dangerous," Mordenkainen pointed to the armored dung maggots in the distance, "These bugs can eat almost anything, except spatial magic. When I first came to the Astral Plane, I wasn't sure of the properties of these things, and I was almost swallowed by them."

Roland looked at the bugs in the distance. Players could revive and were allowed almost unlimited room for errors, so he didn't have much of an intuitive sense of danger, but rather the thin layer in the sky indicating the boundary aroused his curiosity.

A boundary formed by spatial magic?
