You assume that I am from a 'world' - a more accurate assertion would be that I come from a galaxy, or a star system. I understand some here use 'world' to mean 'dimension' but this would be needlessly confusing when dealing with those from places where space travel is more mundane.

And though I realize space travel and 'magic' tend to be repelling poles, I assure you I have seen both, though practically speaking, I believe magic is merely science that hasn't quite caught up yet.

And you've assumed that I expel waste at all - I have met several species that do not do so in conventional ways, or live in closed bio systems.

...Incidentally, yes. There is a refresher station behind that door to your right.
