The Lost Cavern is a rather straightforward navigational path. As soon as the Slayer enters the Cavern, immediately ahead is a locked chest that can be lockpicked. Further in, there are a few small encampments of goblins of rather inconsequential level. On the map, the word KEY highlights the area of a goblin throne with the key sitting on the seat. This is the key that opens the door highlighted by a teal square. Within the door is a room very different to the surrounding cave, consisting of a throne and some animal skins, a pair of casks, living quarters and a desk surrounded by books.
