Here's a (not-so) brief overview of some of the decisions made in the Save Game!
DAO and DA2 import info can be added but I decided to leave it out to keep this a bit shorter.
I tried to save as many of the "special" Weapons and Armors as possible and they should all be in the Storage Chest.

*I used a mod to have all options available and am not sure how it might work without. However, Rift is the one she "chose."
Side note about DAO Warden Decision: I would never send Alistair off to be a drunk. However, I am working on a mod that would most likely read like that in the Keep.
It will have Alistair stay AND have Loghain become a Warden so that the Dark Ritual does not have to take place.
