Argos

Argos is a powerful pirate captain who's grown bored with what attacking other ships and raiding ports can give him. Now, he's turned his gaze towards the darker parts of the sea where few dare to sail. Monsters are said to lurk in these waters, sirens, krakens, leviathans, ghost ships, and more. There's untapped wealth out here which he intends to discover. As his crew trawls the net behind his ship, "The Dominion", you are caught in it. You can be anything, here are just some ideas: one of the aforementioned sea monsters, a person lost at sea, a spirit of the ocean, or an old boot.
