Aasimar

Aasimar are placed in the world to serve as guardians of law and good. Their patrons expect them to strike at evil, lead by example, and further the cause of justice.
From an early age, an aasimar receives visions and guidance from celestial entities via dreams. These dreams help shape an aasimar, granting a sense of destiny and a desire for righteousness.
Each aasimar can count a specific celestial agent of the gods as a guide. This entity is typically a deva, an angel who acts as a messenger to the mortal world.
While aasimar are strident foes of evil, they typically prefer to keep a low profile. An aasimar inevitably draws the attention of evil cultists, fiends, and other enemies of good, all of whom would be eager to strike down a celestial champion if they had the chance.
When traveling, aasimar prefer hoods, closed helms, and other gear that allows them to conceal their identities. They nevertheless have no compunction about striking openly at evil. The secrecy they desire is never worth endangering the innocent.
An aasimar, except for one who has turned to evil, has a link to an angelic being. That being—usually a deva—provides guidance to the aasimar, though this connection functions only in dreams. As such, the guidance is not a direct command or a simple spoken word. Instead, the aasimar receives visions, prophecies, and feelings.
The angelic being is far from omniscient. Its guidance is based on its understanding of the tenets of law and good, and it might have insight into combating especially powerful evils that it knows about.
As part of fleshing out an aasimar character, consider the nature of that character’s angelic guide. The Angelic Guide tables offer names and natures that you can use to flesh out your character’s guide.
