Keywords are:  'spheres portfolio domains'

Gods typically have a number of spheres or domains with which they are
affiliated.  These spheres are representative of the god's portfolio
or are concepts over which the god is expected to exert authority.

Most spheres are made manifest in the supernals of a particular god.
For example, Dowart has the 'ocean' sphere, and as such his supernals
cast 'riptide' during combat when water is available.  The goddess
Byung has the 'undead' sphere, and her supernals are type undead, with
all of the advantages and disadvantages as such.
