Tammy: Actually, my gods, like the gods in most pantheons, have their strengths and their weaknesses, their prejudices and their feuds–they’re just enacted on a much larger scale.
As far as why Mithros and the Goddess came into the Isles, it was just another move in the game to them, another way to screw the kid brother who was being kinda lazy with his humans. Look at the way Juno treated Zeus’s affairs and the offspring of those affairs, or the way the goddesses bribed Paris to give them the prize for most beautiful (isn’t the bribing of the judge so not kosher?). Or the way Hanuman scampers off with his sibs’ belongings. And while the gods’ strength comes from the strength of their worshippers, they can only influence so much of their worshippers’ behavior (the crossroads in time, when humans must decide what will influence the power in the Divine Realms). It makes things a little more even between humans and gods.
Besides, the Goddess doesn’t even show one face to her believers–she has three official ones, after all. Alanna’s only ever seen the Mother, but that’s just one case. And I can see Mithros having his off days.
These aren’t monotheistic gods, but pantheistic ones, dreamt by people to cover each of life’s many facets, instead of being responsible for all of them, like the monotheistic gods are. That sort of thing leads to never being able to figure out why God let something like the death of a child happen.
