Sorcerous Space

Sorcerous Space, also known as Alien Wizard Wars, Extraterrestrial Arcana, or, most popularly, Wizards Continue To Be Dicks Among The Stars, is a /tg/ homebrew setting where Humanity and Earth have the noble distinction of being inside of a cosmic Anti-Magic Field while all or most other races in the galaxy have been using magic for pretty much everything. Humans discover the extraterrestrials or vice versa, and then become elite mercenaries.

Kind of like Veil of Madness if it was smaller and prevented magic instead of other sentient life.
