Secret Tropical Island Volcano Lair (Sauceror)
From A KoL Wiki
Quest Text
As you row up to the island, what immediately catches your eye is a huge gleaming construction of glass and metal (that you guess must be some kind of building, or massive abstract sculpture, or both), which is built up to the side of the volcano.
You spot a small boat pulled up onto the beach, and park near it.
