[@trenenp] That's the simplest part of the equation; most if not all our characters should resemble demigods in power.

If your character is a literal demigod, the child of a god and a mortal, that would depend on where they come from and what "rules" the gods (lower case g) of their world function by.

In Magic the Gathering, there is a Greek-style god by the name of Kruphix (their fantasy Greece's equivalent to say Janus) that describes the gods of their world as "a localized phenomena" in the scope of the multiverse which is what distinguishes gods from Gods. The latter exist outside of their home universe, the former are features of said universe.

Does this make it any clearer/more helpful?
