Minrothad introduces a merchant class and The Sea People adds sea elves, tritons, and mermen as PCs.


Taken together, these three books cover over twenty islands as well as detailing the undersea kingdoms beneath the waves. A GM willing to do more work could even run an undersea setting using the Creature Crucible: The Sea People. The Minrothad Guilds provide rules for merchant PCs as well as details on acquiring a ship and crew and engaging in cargo trading. Player characters might be tourists drawn by the charms of the Kingdom of Ierendi or merchant explorers of the Minrothad Guilds. An entire campaign could be connected by nautical adventures.

Basic D&D and Dungeon Crawl Classics explore fantasy seafaring and the Sea of Dread is well detailed above the waves and below.
