Thanks Maximo. In their introductory session I had the scholar flee Stygia with some other acolytes and his master, and a lot of them were killed in Shem. When I ran them through Kovag Re in their second adventure, I re-introduced some information about a villain who was trying to kidnap/kill/do nasty things to the Stygians. But I haven't given him a face to face encounter yet, was saving that for a higher level. But I think you may be right, it may be time to up the threat level to try to bring the (3) players together.
