I do know it seems like a wild guess, but could it be that the Inquisitor is meeting the Others in the Prison of the Chantry? It looks very similar, I mean they could just reused the set. But especially the Disband Ending would make sense, Haven is Abandoned, thus perfect place for secret meetings.
In case you did not notice, Haven was destroyed during the course of the game and there was no mentioning of it being rebuilt. I think it is just a reused asset for nostalgia reasons (the Inquisitor, Leliana and Cassandra together planning the next step, like at the start of the game). 126.96.36.199 (talk) 18:09, September 11, 2015 (UTC)
