I'm brewing an adventure to GM 7th Sea on Halloween, inspired in the first Pirates of the Caribbean movie. Since we don't have enough information yet to play in the New World, I'm considering how to insert a cursed pirate crew out of the coasts of Théah. I initially thought of place the action in ghostly Eisen and The Maw or Grumfather Bay, related with the ruins of an ancient Sirne city. But then it ocurred to me that maybe it would work better with kind of a Sidhe Curse and a sunken city. I mean, I thought about using Tir-Nan-Og, and wondered if there's some paralell in Théah (there seems to be a paralell for everything) out in one of the 1st edition books. Also, thinking about the source of the curse I wondered about the relationship between the Sidhe and the Sirne, if there's one. Any discussion, indications or even suggestions to spice the adventure will be more than welcomed. Cheers!
