Shadows of the Abyss

A nautical horror adventure for 5th–6th level characters, compatible with Old-School Essentials and D&D 5th Edition. Hired to investigate ships disappearing near Isla Zardia, the party crosses storm-tossed seas before becoming trapped in a cursed ship graveyard inhabited by sahuagin and other aquatic threats. The adventure features underwater combat, environmental hazards, celestial puzzles, and a multi-stage ziggurat crawl. Players must uncover the source of the dark magic, manage limited air supplies, and confront a shark demon and its cult in a pocket dimension. The module includes pre-generated characters, new monsters, and rules for underwater encounters.
