Originally a loose society of disaffected by the 7 sects of Aasimar worship of their Archangel ancestors living on The Whispering Forest floating island on Winged World. Most voluntarily isolated themselves with their fellows, however all held resentment for the intolerance of Aasimar society for those unwilling to bow to their ancestor gods. Helped along by the Archdevil Areth this resentment came to a boil during The Reckoning when aided by Areth's infernal legions the outcasts began an armed rebellion against the 7 sects setting off a civil war which raged long after Areth's death, splintering Aasimar society. The outcasts are now called the Fallen Aasimar by the other factions, however they themselves consider this name a slur and instead call themselves the Free Aasimar for they have cast off the chains of religion and are now as fanatically anarchic and atheist as the other Aasimar are ordered and religious.
Many of the more peaceful and pacifist Free Aasimar are using Spelljammers ships to escape the near constant conflict on their home world and find a new home in Wild space. Most of the militant Free Aasimar are unwilling to give ground on their world, yet a few have taken the opportunity to spread their ideology to the rest of the universe, often actively searching out conflict with religious people of all races.
