Sea-Crossed Lovers:A Nightkiller fanfic

So this is sort of going to be an AU version of the ship in a more experimental way. Like a kingdom&sea AU of the ships. It's experimental so I'm just seeing where I take it.

Once there was a young prince named Nightmare that was known for his pearly white bones always clutching a book and dressed in purple, hiding in the shadows of every ball while his brother shines and socializes. Across the seas is a tavern worker named Killer known for trouble, just trying to get by with his sea-side business. Divided by an ocean and status, they seem to have nothing in common. But little do they know that they share a curse each time the sun goes down, sending them underwater with a strange transformation that secretly links them to the rumored beasts of the seas. So when this prince is sent away across seas and crosses paths with this tavern worker, what will unfold? And what will become of their secret or their curses? Read to find out!

And in case you haven't caught on already, this is a Nightkiller/Killermare fanfic. If you don't ship it, don't read this or get angry in comments about it. Otherwise, please enjoy.
