Something I think I haven't mentioned enough: There's almost no light in the Lair. Currently Loklafd has a Torch. I think everyone on Mord's team (including Mord, right?) has Darkvision, but Kalorn, Primus, Loklafd, and Sesto do not. They'll require Loklafd's Torch. Though I suppose it could be argued that Sesto got a light spell going before he ventured into the crack... I'll give it to you. Though if he cast it on his shield, it's probably on his back. Correct me if I'm wrong, Prickly, but I think Sesto wanted his hands free while climbing...
