|Examine||A closed overgrown dungeon entrance.|
Fyburglars trees are noted for their ability to grow virtually anywhere. The specimen west of Brimhaven can be found growing on the ancient stone entrance to Brimhaven Dungeon, where its roots have virtually fused with the rock.
When talking to Saniboch, the tribesman who guards the dungeon entrance, the player has the option of mentioning the tree to him.
- The name Fyburglars is very similar to fiberglass which many fake props can be made from, implying that Saniboch created the "tree" to trick adventurers into paying him.
