A Voltron Mermaids and Sirens AU, a young siren decides to defy his territory's wishes and cross the border, ignoring the centuries and centuries of mutual hate between merpeople and sirens and he discovers that mermpeople aren't all that bad... Unlike in actual mythology, the sirens aren't a bird-like creature but rather have shark-like tails and such. This whole story is heavily based and inspired by an rp I'm in with a friend, her profile is linked in the very first chapter so credit to her too! Beware of spoilers!!
