In many ways, the Aasimar are the opposites of Tieflings in almost every regard. The Aasimar are born from when one of the angels impregnates a mortal, and the essence of the angel is passed into the bloodline. Similar to Tieflings, the first child of such a pairing may not yield an Aasimar – the Aasimar may not surface in the bloodline for several generations. What triggers the angelic transmutation of a child to an Aasimar in the womb remains completely unknown. Aasimar, similar to Tieflings are extremely rare, but more and more seem to be being born.

There are also three varieties of Aasimar that exist:

Protector Aasimar which has the Radiant Soul ability. The calling of the Protector is charged by the powers of good to guard the weak, to strike at evil wherever it arises, and to stand vigilant against the darkness. From a young age, a protector aasimar receives advice and directives that urge to stand against evil.

Scourge Aasimar which has the Radiant Consumption ability. They are imbued with a divine energy that blazes intensely within them. It feeds a powerful desire to destroy evil — a desire that is, at its best, unflinching and, at its worst, all-consuming. Many scourge aasimar wear masks to block out the world and focus on containing this power, unmasking themselves only in battle.

Fallen Aasimar which has the Necrotic Cloud ability. Typically, the Fallen Aasimar is someone who was touched by dark powers as a youth or who turns to evil in early adulthood can become one of the fallen — a group of aasimar whose inner light has been replaced by shadow.

Most Aasimar, but not all, may have a unique trait about them that gives a hint of their celestial bloodline. Below is a random table as an example:
