Far Beyond Faerun
A cave inhabited by Goblins and bugbears, previously lead by a bugbear named Klarg. After local adventurers killed Klarg, they struck a deal with a more peaceful goblin named Yeemik.
Yeemik now leads this cave, causing trouble in the surrounding areas but leaving Triboar Trail and Phandalin alone.
The cave has a natural stream running through it
