Age. Divine Beings reach physical maturity in their late teens and live for 100 years naturally, showing no signs of age. When they reach 100 years of age they continue to live on sustained directly by their godly parent or if their godly parent does not wish to they may sustain their selves through gaining their own renown and worship.

Alignment. Demigods are as varied as their mortal and godly parents, although they always feel a strong inclination towards the alignment of their godly parent.

Divine Beings vary in height and built due to their humanoid parents coming from a variety of races, however, they always appear within the taller ranges and stronger builds of their mortal sides race. Regardless of your position in that range or your parent's race, your size is Medium.

Mortal Parentage. Even though it is your godly parent that makes you special, you still have a mortal parent. While you don't receive any of the racial traits that your mortal parent has. Your mortal parent must be humanoid and you physically resemble that race in its most epitomized form.

Portfolio Sense. Divine Beings have a limited ability to sense events involving their portfolios. You automatically sense notable events and minor events within 5 miles that involves your portfolio. When a Divine Being senses an event, it merely knows that the event is occurring and where it is. The Divine Being receives no sensory information about the event. For example, if a Divine Being of the nature portfolio was within 5 miles of a forest fire it would become aware of it and where it is happening. If it was 10 miles away it wouldn't have any idea but if that forest fire broke the seal on an ancient evil that their godly parent or some other nature god locked away you would become aware of it as well as the location of the site.

Languages. You can speak, read and write Common and all Divine Beings have the innate ability to speak, read and write Celestial. Whether they discover this through meeting an angel or when a traveling Aasimar got a peek at their scribbles as a child is, it is ultimately up to you. Celestial as a language sounds like a heavenly choir when spoken, and is written with a grace and fluidity that no mortal language has replicated.
