We heard that there were some Dragon Cultists looking for a Shar Cultist hideout as it may have information in finding the dragon. We found that hideout and went down the long shaft deep underground. We ran into quite a bit of trouble while we were down there. There were monsters and such, undead that almost killed us, but more interestingly and more disturbingly there seem to have been some spells that used the shadow-weave to power them. I am unsure on how to counter these magics and must do some research at the library.
