Hyperspace

A dimension alternate to our own. Because of slightly alternate laws of physics and chemistry, it’s absolutely lush with life. Short distances travelled here correspond to larger distances in realspace— A useful property for faster-than-light travel in the Milky Way, provided you keep your ship to the sections of space that mostly abide by realspace physics. Wander outside those ranges and your body starts melting. The same used to be true of hyperspacers visiting us, until one species, the Visitant, figured out how to modify themselves into compatibility.

Most characters here are Visitant– one of my original species that I currently have minimal posted lore on.
