Head up northwest between the cliffs and round the corner to the southwest

You will see a cave martial empires gold entrance just before you enter between the cliff paths to Death Plateau (the cave won’t be indicated on your mini-map).

Enter it and talk to Saba, a disheveled and irritable hermit. He’ll tell you to find and talk to the sherpa who might know of another path up Death Plateau (if you head up the main path, you’ll be battered with rocks by the troll throwers uphill and might die).

To find the sherpa, head out of the cave. Head up northwest between the cliffs and round the corner to the southwest (at the area where the injured soldier is).

Open the gate and knock on the door when you reach the house containing a chicken pen. Tenzing, the Sherpa, will tell you that he doesn’t want any milk today, assuming that you’re the milkman. Your character will ask for his help, so he’ll tell you to come in.

Tenzing, apparently, does know of a secret path up Death Plateau, but he’ll only be willing to tell you the secret if you can obtain for him 10 loaves of bread, 10 cooked trout, and to have Dunstan, the blacksmith in Burthorpe, spike up his climbing boots.
