Glain, the Dwarf who led the PC's to corovaxinar, armored up and joined Zaldar as a follower
Zaldar and Glain went to the Armory to defeat the Warlock Knight
Zaldar used an illusion to pretend to be the priorly defeated Knight to send the Armory Knight and away. The ruse worked, leaving only two Duergar and two Chain Devils to defeat.
Faradur (PC), an elven captive, was freed and joined the fight
Zaldar, Faradur and Glain defeated the Duergar and Warlock Knight at the Armory
The group then went to the Barracks, the last place to liberate in the "Iron Fell mines"
The group was ambushed by two Ice Devils, a group of Goblins and both the Barracks knight AND the Armory Knight
The session ended with Zaldar, Faradur and Glain at the verge of being defeated.
