Krug finds no further traps in this part of the Banewarrens. The lamia regains her senses before long, but puts up little struggle when she realizes that she is captive. You notice she has several injuries (probably from the fight with Kalerecent).
You learn that the lamia's name is Derimach. She admits that she and her companions have an interest in the Banewarrens, but she refuses to say more about it. She also confesses to opening the doors to the south, releasing a drow elf and opening the door to a enchanted block of ice.
Leaving the guardian in the next chamber undisturbed, you have completed your survey of this part of the Banewarrens. After hoisting the lamia out of the pit, you return to the entrance and prepare to make your way back through the tunnel.
Despite your normal awareness of your surroundings, you are surprised when a second lamia and a minotaur come charging out of the tunnel entrance, leaping to the attack.
