Aasimars are typically humans with a significant amount of celestial blood in their ancestry. While not always benevolent, Aasimars tend to be more inclined toward acts of kindness rather than evil, and they gravitate toward faiths or organizations associated with the divine. Aasimar heritage can lie dormant for generations, only to appear suddenly in the child of two apparently human parents. The combination of celestial and mortal flesh is not without its prices however. Most Aasimar live a half-life of sorts, after they awaken the celestial portion of their being begins to burn up their mortal half at an increased rate. This results in the lifespan of an Aasimar's mortal race being cut in half, they do not incur the effects of aging faster than normal but instead usually die young from the mortal half of their physiology giving out. There is however a very rare anomaly that sometimes occurs in half-human Aasimar where the potency of the celestial parent actually extends the life of the Aasimar rather than shortens it.
