Worms On the Heights  

You will need to stand on the cliff look west and type /look

The Forgotten Monument is on the peak of the cliff east of Echad Candelleth. You get up there by going up the hillside northeast of the burnt up cottage on the east bank of the Bruinen river. You'll go up a ways passing dociles and orneries as well as worms. There will be a fork where there are trolls to the left, go up the right and once you get to the top curl around to the right along the cliffside. You'll see a stone gazebo ruin, that is the monument, straight east of there are nests of worms and Sarlug is in the middle of them. He can be pulled solo, but all of them are level 42 non-signature worms.
