Mystery and Death Await You in the Sunken City

Sunken City is a Fifth Edition adventure optimized for three to six characters of 8th level. Full of oceanic monsters, ancient mysteries, and unique puzzles, this adventure is perfect if your table wants to dive into an Altlantis-like mystery.

This is a unique adventure, containing twists and turns to surprise your players. Full of Atlantis vibes, with new monsters from the deep ocean specifically created for the adventure, and all the things you'd expect to find from an ancient ruined civilization. This adventure is for level 8 adventurers ideally, and can be used perfectly to take a break from your main campaign, or as side quest to an existing world, or to run if your players find themselves in need of LOOT

This adventure can go either way, and either reward your characters handsomely, or rob them of their sanity.


A long, long time ago, before the current age of man, when the sea is seen as treacherous and unyielding, there was an era of harmony with the waters. The entire civilization of the Comboro Isle built temples to the gods of the depths, and these gods rewarded them with wealth and great luck. And then, through events unexplainable even to the most intelligent of scholars, the Comboro Isle sank to the bottom of the waters, and the Evermist arose. Since then, the Evermist has veiled the seas, sinking any ships that dare venture far from the shore. But now, a daring explorer has begun looking into the ruins of the Comboro Isle. And he requires aid.
