[God of War] Do Gods choose the aspects of the natural world that they have dominion over are the titles something they are born with ?

Did Zeus and other Gods become the gods of sky, war, etc. because of their natural abilities or were they roles that were taken as they matured? A second question is what is the source of power for the various pantheons?

From what we have seen so far, it is a title. Ares was GOW till his death then the title was vacant and was given to Kratos. The power is something they have or acquire via learning magic or magical items. Hermes had magic boots, Poseidon seem to have used magic to use lightning and water magic.
