Casmund | Siren (mermaid x pirate au)

Edmund is a mysterious shipwreck victim rescued by a ship in a dangerous line of work. Caspian is a pirate captain who has heard legends about merfolk shapeshifting to trap sailors--and hoarding treasure below the waves. Both intend to gain the others' trust and steal his riches. It's not like HE'LL get emotionally entangled himself, right?
(wrong, they are both getting it BAD)
This is based on a fic I'm writing, which I wanted to have done for Mermay, but, alas, I do not write that fast. I can apparently whip out a video in four days, though. (thank you William Moseley for being in a mermaid movie so I already had the files on my computer lol) I'll add a link here when I get the fic done; for now there are a few snippets and an aesthetic on my tumblr under the tag "narnia merpirate au" if anyone's curious.
