There would be no humans, but there are races in the works that would be similar enough to humans in outlook to fill that niche.
By vastly alien, I meant more along the lines of different than traditional fantasy. No elves, dwarves, humans, etc... There will still be races that you can identify with, and races that fill the niche that those races fill as well.
The world is going to be millions of years after the fall of a technologically advanced alien civilization. "Magic" is going to be the manipulation of energies that emanate from the planets core. All spells fall under this "magic" as there are no "true" gods, although there is religion and some of these "mages" believe their ability to manipulate the energies to be god-given.
Another question then:
What would YOU like in an Alien Fantasy setting?
