After you fled the Bîaŵac to this ruin, the entrance of the ruin collapsed and you need to find another way out.
If Heodan was injured from the previous quest, he will request that the group Rest before continuing on, while Calisca insists that you press forward. If you do rest, Calisca will leave the group. Oddly enough, if Heodan is uninjured, resting will not cause Calisca to leave the group.
In the north of the ruin you find a floor puzzle, you can either deactivate the traps with a 3 mechanics skill or go to the left room and light the pillars with torches or Flint and Tinder to deactivate some traps.
To the west of room with the pillars is a room with black oozes and an interactable stone relief of a man's face. If you have the waterskin (received automatically if you didn't kill everyone in the caravan during A Moment's Respite), and an Engwithan Relief Gem, you can put the gem in the face to open a secret room, which contains a Minor Cloak of Protection.
East of the floor puzzle is a breakable wall, and a corpse containing some items, including the Engwithan Relief Gem. You will need Calisca, high Might or Hammer and Chisel to break the wall. Behind it is a room with a few Skuldr; leaving the room through this western exit will enable you to bypass the floor puzzle entirely.
There is also a Xaurip in the south east. You can interact with it, but if you come near it, it will attack you. If you've killed the Skuldr you can opt to give him the flesh that was dropped for a non-lethal method of getting to the container behind him.
Behind the floor puzzle is a room with a Spear Spider and you need to cross this room to exit the ruin. Leaving the ruins completes the quest.
