Caverns of the Goblin King: An 8th Level Adventure for 5th Edition

The Slimetongue goblin tribe has long called the swamps of the southwest home. For years, they have plagued the trade roads with minor raids and troublesome blockades, but more often that not, they have been easy to chase off back into the wetlands they came from. Recently, however, their raids have become more organized and their attacks more brazen. Fearing the roads between the dwarven kingdoms and the elven ones could become completely unsafe, calls have gone out for adventurers to plumb the depths of their swamp stronghold, seek out their leader, and either negotiate a peace, or deal with them once and for all. Unbeknownst to those outside the goblin caves, the tribe has come into possession of a powerful artifact. Emboldened by its effects, the goblin speaker, leader of the tribe, has instructed his people to go forth and take from the pink skins whatever they can for the glory of the goblin tribe!
