It should have the game as the prelude to Pillars of Eternity .
It should be about the Saints War and a young Durance and his Party that slayed a God with The God Hammer.
The game should be darker, gritter, and more mature.
Of course your going to need Chris Avellone back on board to do the writing for characters like Durance. (contract for hire)
There could be a young Eder in there too.
Just going forward with another location etc isn't that great of an idea. it's time to create the Story that is told in Pillars.
Good Luck!
