The windswept tree. Dig in the shaded area for entry to the Cave.

The Brine Rat Cavern is a series of caverns which feature heavily in Olaf's Quest. It can be entered after starting the quest by digging south of the windswept tree, on a plateau east of Olaf Hradson and south east of the Rellekka Hunter area with a spade in the inventory. After digging the hole, the player will be stunned for a few seconds.

The exit to the cavern is found in the south-western side, blocked by a rock. Rolling the rock will expose the exit.

Boulder at cavern's exit

The cavern consists of a mixture of interior and exterior areas. The main cavern and the area at the end of the cavern are separated by coastal areas and a slippery walkway.


The Brine Rat Cavern is in the north-eastern region of the Fremennik Province. This is a remote area and takes some time to walk to. There are some faster means to get here:

The entrance and exit to the cavern can be found in the south western corner. There are many monsters which make their home here, such as giant bats, found in the passage closest to the entrance, and brine rats, found in a cavern just east of the giant boulder.

Skeleton fremenniks can be found scattered throughout the northern half of the cavern. They hold a key that must be obtained to bypass locked doors further in the caverns.

The picture wall that separates the first cavern from the first coastal area is a puzzle door that must be solved during Olaf's Quest. After completing the puzzle it remains open.

The coastal area to the far north of the cavern contains more skeletal fremeniks and rock crabs. The eastern coastal area contains rope and rotten barrels and the western side contains a shipwreck formerly captained by Ulfric Longbeard and the captain's grave, just east of the wreck. The two areas are separated by a slippery walkway and a door with multiple locks.

Searching the chest in the wreck will cause Ulfric's reanimated skeleton to attack. After he is defeated, the chest can be searched again to loot Ulfric's treasure.



Ulfric's Shipwreck

The shipwreck.

  • It's possible to see the part of the cave with Ulfric's shipwreck with the Orb of oculus from the Rellekka Hunter area Polar Eagle Cave. Walk toward the end of the southern eagle's nest, and go east with the orb. Eventually (and with fullscreen), you can see something like the picture to the right.
  • Examining the boulder at the cave exit reads 'Keeps rolling, rolling, rolling...' This is a reference to the Limp Bizkit song Rollin'.
