Ignis Fatuus, otherwise known as will-o-the-wisps, are little known creatures born of magical energy that use their appearance and powers to spread bad luck and inconvenience to the unwary.

Cultivators, an offshoot of the species, can be created by dungeon cores to draw essence and other energy from one area to another to spread their influence and encourage growth within the dungeon. The ability to displace and convert these energies is an incredible power, and given time could lead to limitless possibilities. If cultivators weren't mindless constructs, they would be an incredible nuisance to the mages of the world.

Khan is one such nuisance.
