Archives of Nethys: Aasimar
Born with the power of benevolent celestial entities, aasimars are thought to be supremely blessed with strength of will, extraordinary beauty, and innate magical gifts. But many aasimars find that these perceived talents—whether they actually have them or not—set them apart from their friends and family, fostering loneliness in themselves and jealousy in others.
Aasimars with a positive outlook face these challenges by serving their communities, populating the environment with kindness or artwork, or simply supporting those who are less fortunate. Some aasimars hold a more hostile worldview, however, and risk falling into resentment, despair, or even the temptations of evil. Even then, the stereotypes surrounding an aasimar cling close, causing others to view them as tragic figures in need of redemption.
The powers and physical appearances passed down from celestial beings vary according to an aasimar's lineage. Those who descend from archons are sometimes known as lawbringers, while those who possess angelic blood are called angelkin, and those related to azatas are referred to as musetouched.
If you want a character brimming with celestial power, unique physical characteristics and the potential for strong faith, you should play an aasimar.
