I finally finished the entire Sahuagin Fortress from Ghosts of Saltmarsh! 🦈🌊

This project recreates all three levels of the sahuagin stronghold from the official adventure, from the unfinished upper halls worked by slaves, through the flooded temple and royal quarters, all the way down to the military heart of the fortress where hundreds of sahuagin prepare for war.

The complex includes:

⚔️ Military barracks, armories, guard posts, and training areas

🦈 Shark pens, hatcheries, and underwater patrol routes

👑 The throne room and private chambers of the sahuagin rulers

⛓️ Prison cells, torture chambers, secret passages, and hidden treasure vaults

🏟️ A brutal arena where sahuagin settle disputes through deadly combat

🌿 Flooded corridors, seaweed-filled chambers, and natural underwater caverns

To make the maps more versatile, I created both flooded and non-flooded versions of every level, making the fortress useful not only for Ghosts of Saltmarsh but also for homebrew underwater adventures, coastal campaigns, or any large aquatic dungeon.

This was one of the biggest mapping projects I've worked on so far, and I'm really happy with how the fortress evolved from level to level, gradually transitioning from worked stone halls into vast underwater military caverns.

I'd love to hear what you think — and if you've run Ghosts of Saltmarsh, how did your players handle the sahuagin fortress?
