To Sink a City

Author: MonkeyDM

Addon: Content which can be added into any game - new or existing!

Death is Certain in this Mission, Make it Worth it!

To Sink a City is a Fifth Edition adventure optimized for three to six characters of 14th level. Full of oceanic monsters, chase sequences, and an intense boss battle that will result with the end of the party, and perhaps the world if they don't succeed!

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 in an end of the world story. This adventure is for level 14 adventurers ideally, and can be used perfectly to take a break from your main campaign, or to run if simply want to kill your players (or at least their characters ;)

This adventure is a very fun experience and although it results in character death, the build-up and apotheosis of the story makes their sacrifice something they'll remember


In thousands of years, the civilization of Comboro will be seen as nothing more than a legend, a ghost story, but in current times, it's the richest in the world. Led by the Priests of the Great Tide, Comboro has grown to extraordinary size and prospered plenty. The entire island is now richer than a large part of the mainland. This is all due to the waters of life, gifted to the islanders by The Spirit of Ebb And Flow. But something has been amiss lately. The sun has retreated and a cloud of mist has slowly risen around. With it, crime rates have increased and sickness has spread. To find the truth about this mysterious weather, the Head Priest, Syim, has asked for aid. He must preserve the waters of life at all costs, he will take no risks.
