For some reason I want to say it's Procipinee, but I only think that because she was kind of a b**** in the E:WoM campaign (can I even call it a campaign hah). Although, that's probably because you played as Relias in the E:WoM campaign and Altar is essentially a breakaway from Pariden - at least, that's what I gathered - which could understandably make Procipinee dislike Relias.
If I can remember correctly, however, she had "recently met with Karavox" or something and refused to believe he had sided with the Fallen races. Going so far as to try and convince other leaders that war was not inevitable and preparing for war wasn't necessary.
I could be completely wrong though, because I'm basing my opinion on the terribly short and outdated E:WoM campaign
