Re: The Inquisitor in the Keep
Nope...whatever tapestry you have active at the time will be continued with the Inquisitor you download it too and run. So basically create the world you want up to DAI, play the game and then you can go back and see what choices were made by him/her then. You don't have to create a character on the tapestry before you make one in game, BUT you can make one if you desire if you want to set up a world state for the next game without having to play a certain way. You can reveal all choices for DAI by choosing the proper setting in the Keep options on left side of screen.
I am pretty sure it bakes whatever data into the keep save for your completed DAI character for all games, but I don't know this 100% and no one knows what will effect the next game at this time.
