Do you go to the dungeon?

Sweem's tunnels

Sweem, a giant rock-burrowing eel, dug tunnels through the city of Kusmra before she was killed.

The opening to Sweem's tunnels were guarded by eight ape-like robots. Five of them were killed by Valdemar, Vailon, Dinek and Lindel but three survived and are guarding the tunnels with their stew of punishment.
