Im in Rimerock burrow and I cant figure out how to go through the dungeon. its just passed a part with a hidden passage in a wall and a trap door in the floor that you can open and close by activating is. I cant get passed the next gate, it wont open and i cant find a lever to open it. Can anybody show me a detailed video walking through the burrow or explain to me what im missing please I feel like im stuck. I thought the game glitched so i loaded up a save just before the burrow and i got to the same spot and the door still wont open.

Did you jump down into the pit, that's the way to go.

After you find the axe, you'll get the key off the axe carrier's body to unlock a door and get back up to the exit.

When I killed the axe carrier his body wasn't lootable, I saved and quit the game and when I loaded my save I could then loot the body. The door has a master lock, so if your lockpicking is good enough you can pick the lock.
