With a back and forth conversation discussing the implications of this, Toun puts forth a theory that explains how the domains and portfolios of demigods come about. It involves three elements:

1. There are 'roles' in the universe that draw divine essence. When a role is not occupied by a god, a new god is born to occupy it. 
2. Gods may draw essences out to fill particular absent roles by willing it so. Most gods either unconciously will the essences to fill familiar roles or simply let the randomness of the universe pick for them.
3. Gods can only really will essences to take roles that are a subset of their own role, but two or more gods can combine their essences to will a new essence into a role that none of them possess in full.

Quite the theory you got there....would be horrible if a certain knowledge god/sin demi-god started conversing and fucking things up.
