You are able to speak Celestial as well as common

Your base walking speed is 30 feet.

Angels when they enter the mortal realm take on the average size of a human. Your size is Medium.

Alignment depends entirely from what plane or realm you are from as well the god that created you. Changing your alignment could make you lose favour to your good and have your celestial powers and race revoked making you the race closest to the description of your character. However if you were to find another god that would take you in they can make you Angelic once more.

Angels do not age at all due to their celestial blood. However if they were to ever stop being a celestial being they would turn to a mortal race and begin to age from the age of 20.

You are immune to Diseases
