I think I would add in that she specifically knows about Minthara's missing expedition, seeing as how Minthara is a Baenre. It makes the potential recruitment of Minthara much more poignant.
I'm also curious what happened at the end there. Is the suggestion that an Absolute faction assassinated Erelunhe and subsequently ambushed Cembrye? Meaning that the Absolute has infiltrated Menzoberranzan?
