I am designing a Dark Sun adventure around the Ghosts of Saltmarsh book, except of course we don’t have seas anymore, although we do have lots of Salt marshes. I will be replacing the water seas with silt seas, and I remade and reskinned the town of Saltmarsh into a town called Harrow Spring. The town is all fleshed out and I will be able to use most of the adventures in the Ghosts of Saltmarsh book. But one adventure called “salvage operation” wants the players to dive into the seas.
I wonder how one would accomplish this in the Silt Sea? I’m pretty sure there are still ship wrecks at the bottom of the silt seas, possibly the wood is petrified or just some of the metals from the Green Age are left.
The Ssurran Lizardfolk I adapted to the setting are able to burrow in silt and sand, and hold their breath, so they would have an easy time exploring beneath the Silt Sea, but I think normal humanoids would need earth moving magic in order to do it. Perhaps another method is that there are pockets of water or caves that can be excavated under the Silt Sea.
Anyways, I’m looking for suggestions as to how to accomplish this.
Here is a link to the Ssurran race that I adapted from 5e Lizardfolk, by combining the attributes of the Asabi from Forgotten Realms that inhabits the desert. If you want to use it you are welcome to. Lizardfolk, Desert (Ssurran) (5e Race) - D&D Wiki (dandwiki.com)
