Aasimar are the
angelic counterparts of
tieflings in the
Planescape setting. They are
pure and
good, according to popular
belief, a fact which many use to their advantage by being
nasty,
sneaky and
evil. Sprung from the various
celestials of the
Dungeon and Dragons universe, they tend to have gold or silver skin, although this is not invariable, and some of them are in fact related to the personal
minions of the gods.
Addendum: The new
Forgotten Realms Campaign Setting includes details of aasimar
Character Creation in
Dungeons and Dragons Third Edition. The new
Oriental Adventures book refers to aasimar as
Rishi, but does not supply rules for their creation. Third Edition also introduces a distinction between half-celestials and the less-than-half-celestial aasimar.
