The dynamic is that the worldwound wouldn't have been possible if Aroden hadn't died. I think Nurah exposes on this if you ask for a history lesson but I'm not sure.But I pointed out the fact that Aroden's death impact seem largely irelevant to the overall narrative of the CRPG.
The thing about Aroden is that his death is the Big Event. Magically or politically, Aroden's death has thrown most of the world into chaos. The human empires that he patronized failed, Sarkoris shifted towards the Abyss, and a bunch of other stuff. Even if it's unspoken it's not possible to be set in this world and have Aroden's death be largely irrelevant.
Sarkoris is like fantasy Afghanistan. A wise man once called it a country of Kabul + large amounts of 'mountain libertarianism'. I can see Iz having a de facto prominence with Inquisitors and such like, a bunch of tribes like Wintersun with their informal agreements forming the base of society, and then a common culture with druidism and the worship of Erastil / Pulura / others at the center. And of course, lots of cultural rifts here and there.Dialogue from the insane dwarf shaman (or was it notes) shows scorn for the Sarkorian who chose to live in stone walls so there is hints of a cultural rift, but it's never expended upon, and completly brushed aside by the dialogues of characters talking of Sarkoris as a tribal confederation.
