The Mouth of Mentius (OSE)
An old-school dungeon crawl set in an ancient underground palace tied to Greco-Roman myth. Across 73 rooms and four levels, characters face puzzles, traps, monsters, alien armies, dimensional sailors, aberrant enemies, and powerful deities. Three warring factions compete for the dungeon’s secrets, allowing characters to fight, ally with, or betray them. The mini-campaign supports advancement from 5th to 10th level and includes emotionally intense NPC relationships, grid-mapped challenges, and high-resolution digital maps.
