Aspect

Aspects, or manifestations, are alternate forms taken on by deities when they interact with the mortal world. Some deities, especially those whose domains cover various elements, may have different aspects to embody those forms.

Notable Examples
Larethian, deity of wisdom and patron of the Elves, has both a masculine and feminine form.

Ioun, goddess of prophesy, and Asmodeus, god of Tyranny, can both manifest in their angelic and demonic forms, respectively, and as dragons.

Erythnul, god of the slaughter, is said to have hundreds of forms, but only six have been recorded by divine scholars.
