What is Angel Physiology?
The power to use the abilities of angels. Variation of Transcendent Physiology and Mythic Physiology. Opposite to Demon Physiology.
User with this ability either is or can transform into an Angel, a being connected to and serving Higher Powers. Most commonly angels simply manifest wings, an inner glow and/or a halo, which is the usual form of which angels are imagined, but there are several kinds of angels who are far less humanoid, some ranging from strange to surreal.
For practical reasons angels can be divided into three groups defined by what they are formed from:
Physical Angels aren't necessarily solid matter, but they are material/energy beings with relatively defined/stable form and often at least somewhat human-like mind. Most users that aren't originally of angelic stock have this variation. Note that angels of this group aren't necessarily any weaker than those of the other groups, they are simply more "solid" in mind and body.
Spiritual Angels are completely spiritual beings, and thus far less bound to the laws of physics or single form. Many of them think in ways that are only tangentially relatable to humans, and their forms are both transient and often downright surreal.
Ethereal Angels are often both the most powerful and ancient angels, in some ways closer to sentient concepts than anything else. As such, relating to them in any way is likely impossible.
