Aasimar

Aasimar bear within their souls the light of the heavens.They are descended from humans with a touch of the power of Mount Celestia, the divine realm of many lawful good deities. Aasimar are born to serve as champions of the gods, their births hailed as blessed events. They are a people of otherworldly visages, with luminous features that reveal their celestial heritage.
Despite its celestial origin, an aasimar is mortal and possesses free will. Most aasimar follow their ordained path, but some grow to see their abilities as a curse. These disaffected aasimar are typically content to turn away frorri the world, but a few become agents of evil. In their minds, their exposure to celestial powers amounted to little more than brainwashing. Evil aasimar make deadly foes. The radiant power they once commanded becomes corrupted into a horrid, draining magic. And their angelic guides abandon them. Even aasimar wholly dedicated to good sometimes feel torn between two worlds. The angels that guide them see the world from a distant perch. An aasimar who wishes to stop and help a town recover from a drought might be told by an angelic guide to push forward on a greater quest. To a distant angel, saving a few commoners might pale in comparison to defeating a cult of Orcus. An aasimar's guide is wise but not infallible.
Aasimar of Paliira are rare, though no less common than their tiefling counterparts. They are often upheld by those in their hometowns as paragons of good, though this usually drives them away and toward their true fate.
