From publisher blurb:
The Goblin Tower is a D&D 5e adventure for 1st to 3rd level characters. It consists of 2-4 sessions in which the players explore a tower and a mine that have been taken over by a goblin tribe known as the Jagged Tusk or simply “The Jaggers”. This motley crew of Hunters, Gatherers and Pariahs are led by their queen, Scoria Grel, and her wizard, the Booyahg Caster called Gas’tunker.
The borderlands have been abandoned, the territory ravaged by ancient wars and left fallow for decades. But this no-man’s-land has provided access for other, more pervasive creatures to infringe upon the known world. Rumour has it that a green and yellow tide is coming, and at its head are goblin tribes that have been pushed out of their own lands by orcs and hobgoblins. Scoria Grel, the self-appointed goblin queen, has already taken her first steps onto the fringes of the law-abiding domain. With the help of her Booyahg Caster, Gas’tunker, she has claimed an old copper mine and the abandoned border tower that stands but half a mile from the mine’s entrance. Scouting parties have returned with reports that Scoria has overstretched her reach and that her tribe is smaller than first expected. There could be an opportunity to rid the land of this pestilence before it spreads any further.
