Underport: Abyssal Descent

A vintage swords-and-sorcery mega-dungeon presents more than 250 detailed encounters across nine or more dungeon levels, along with a small pirate village and two underground keeps. Compatible with OSR and d20-based rules, it supports parties of five or more adventurers across challenges ranging from 1st to around 16th or 17th level. Encounters are not designed to be balanced, so players must judge when to explore, fight, or retreat. The setting features heavy combat, chaotic dungeon exploration, and an artifact with a Wild West-inspired origin.
