Azatas
Azatas (pronounced ah-ZAH-tah) are a type of benevolent celestials native to the plane of Elysium. Azatas are champions of goodness and manifestations of freedom, and choose to travel the planes helping creatures in need and battling evil. However, they tend to avoid meddling in mortal affairs since doing so could impinge on those creatures' own freedoms. Azatas do not believe that evil can be completely destroyed by methodical campaigns, instead devoting themselves to showing up where they are needed most, doing their best to help, and then promptly leaving.
Azatas are formed from the joy and beauty of Elysium and the constant supply of goodly shades from the Universe, who often spend some time as a half-celestial before becoming an azata. Like most outsiders, they cannot procreate with each other or with mortals, but will happily engage in short-lived relationships with them. Azatas are always looking for those of kind hearts and light spirits, and seek companionship among them whenever they can, but never for very long.
