By the way,what happened to Garas?
What do you mean? He's at the same place where he's been ever since he left Sirion?
In case you're referring to the fact that Catherine is now ruler and not Garas? Catherine's his wife and it happened during time I was very busy IRL, plus we hoped it would make a good impression with the rest of the north (the latter failed, but it still added quite some extra flavor and stuff). Garas remains Duke though (and General again for a while now).
