Captain Grot’s Treasure

The corner of a page is hanging out of Captain Grot’s pocket. Upon further inspection, it turns out to be a map of the area, crookedly sketched by an orc hand. A square and a tree are drawn inside the outpost, and something resembling a key is above the lake. If you take a good look around, you could profit from this pirate’s treasure. The captain doesn't need it anymore.
