So now, I've got three to bring out: Athena, Amber, and Sam. The name Athena actually came in the dream. The names Amber and Sam just feel right. The characters aren't necessarily all linked to one another, though Amber and Sam at the least are. And even if they are, heck if I know where they'd be. I don't have any preexisting stories which they are definitely in, nor do I necessarily have the material where they'd have a story of their own.
But I'm happy all the same.
