Publisher's blurb: The city state of Thentia is plagued with relentless storms, with no sunlight in sight. The local wizards believe that the weather may be linked to a sunken ruin and the previous expedition has gone missing. Will the party be able to rescue the adventurers and clear the skies once and for all? This two-hour adventure is designed for Tier-1 characters and optimized for level 3s. Additionally, it can be extended into a four-hour game by using the optional objectives included, or expanded into a multiple session homebrew game using the adventure hooks. Featuring an underwater dungeon, this quest will challenge your table with a different style of combat, as well as offer multiple puzzle, roleplaying and exploration possibilities. Inspired by the "Tomb of Annihilation" adventure design, it's primarily focused on dungeon crawling, with a unique boss battle at the end as well as a plethora of secret rooms and passages. The module first premiered at Tabletop Scotland, 2019.
