I wasn't sure where to post, but given that I want to check for interest, I believe I'm at the right place.

Like the title mentions, I plan to make an RP where RPers will play as marines. Most of the ones I've seen are about pirates and adding to that might not garner as many people.

The general setting of the world is that Blackbeard eventually plunged the world into an era of anarchy, causing a proliferation of pirates and criminals. The marines initially were spread thin, but crumbled in the end, allowing pirates to freely sail across the seas. Most islands and kingdoms isolated themselves from each other and closed their borders to the world, in hopes that they could survive on their own.

Lasting for far too long, a number of individuals rose up and reestablished the marines, but it won't be as amazing as it used to. Without any choice, aside from those who truly believe in justice, the ranks of the marines will be filled with everyone and anyone who wants to help make the seas peaceful again. 

That's what I have for now. I'm willing to brainstorm with others who are interested.
