Where is zak on horseisle?

Answer 1

AlmostSane from Brown Server:

Zak is found on lava isle on the bubble/bump southwest of the large maze. If you're looking at lava on a map it's where the little maze is (not the main maze). Travel south of the little maze and walk along the coast until you see a lone palm tree. It's the only one there besides a double palm tree so you shouldn't have trouble finding it. zak is south of the palm tree (if you stand under the tree dismounted it's 1 step to the coast).
