Meruka is generally monogamous (she's got too much other stuff to do besides have multiple relationships), but Lucanis and Spite are her exceptions.
My Teiagomancer Rocio is, obviously, poly, though she hadn't realized it until she fell in love with two people at once.

Are any of your OCs polyamorous? Would they be open to it?
