Not sure if i can answer, but i will try. I've tried searching for clues for some time but there's little to go on, most of the talk on various forums although with good intentions turns out to be gobledegook. It's mostly boy-talk/theory/fantasy.
Yes there are three divinities, and.......yourself, so between the four what method can be applied to appease those three gods considering that you are given some power to change sides?
1. Side with Innos or/and the sub division of that class.
2. Side with Adanos or/and the sub divisions.
3. Side with Beliar and/or the various affiliates (orcs hashishin) etc'
4. Go it alone. (no info's on this anywhere yet)
Siding with one god could make the other remaining two combine - - but only momentarily (so as to oppose) then with the other pair/s when appeased, complicated? - you bet, especially when neutralising or should i say 'utilising' the sub denominations eg: summoning, transforming, etc' - suggesting that at some point in the game to change your denomination to fulfill the purpose - what purpose? - more later maybe as the storyline evolves.
The whole game essence and concept revolves around this core subject as stated by Kai Rosenkranz, i wish i could understand it and yet the clues are all in there, it's just a matter of time before someone hits the right combo' - maybe.
If any player doesn't understand all of this, put in simple terms - "solving the quests by other means than killing/hostility" will yeild the god pleasing result, the desired, strongly hinted aim of completing G3 (as was G1 and which i have now come to understand - because of G3 !!) and restoring the lost balance as mentioned in no uncertain terms in the books of ancient knowledge.
There are three end results to the G3 game, how many of us will see the light, the right path.?
