So, a fun thought that just occurred to me:  After the devils are dealt with, suppose Elvas'thrae were to return to his quarters to find the previous House Mage's apprentice (http://www.myth-weavers.com/sheetview.php?sheetid=334068) waiting to serve under him?  I'm not actually trying to get to play Antimony again, of course, it just occurred to me that it wouldn't be all that difficult to introduce her into the plot if I were.  And thinking about what uses she might wind up being put to under Elvas'thrae is kinda fun...
