From publisher blurb: The mysteries of the deep sea go beyond human capacity to understand or achieve. However, nothing compels them the impossibility to reach us. The Curse of the Depths is a one shot adventure written entirely in one page. It can be played with any generic RPG system and you are going to need a player to be the Storyteller (Game Master a.k.a GM) and 4 to 5 players to take the roles of the Playable Characters (PC).
