I believe we saw Queen Vlaakith CLVII, in a video that is a epic encounter.
Old time dnd player here as well, if back in the day Neverwinter nights 1 and 2 could do it, I know Larian can.
Im sure they want to keep some things under wraps and I believe they could be in a holding position waiting to see how the game sells and the review of the full game.
