Unfortunately, I'm kind of terrible at pitching ideas, but here I go:
Since I offered my interest before, and sort of forgot about this, I suppose I'll pitch my idea for an antagonist, though I perfectly understand if you'd rather have all the players playing as Brand's adoptive children. I have no intention of creating a villain that will overshadow King Harold (demon-possessed or not), since it's obviously far too early in the story to over-complicate things. If I have the go ahead, I envision him as the villain of a beginning "arc", in which he may be killed at the end of the arc (or not, depends on what happens). I was going to have him be the younger brother of King Harold, but I'll need some more background information on Harold as well as the country. Not a lot, but mostly basic things. Obviously he'll be much more of a mixed bag than Harold, and he'll have equal moments of cruelty and kindness, but that's more to say that he still possesses an amount of his humanity. He's a deep thinker and often has a twisted sense of humor, and sadly, he's put his lot in with his brother long ago, and is beyond any kind of redemption. So that's basically my pitch- younger brother of King Harold who comes into contact with the adoptive children of Brand as their first true adversary. If you'd let me actually make the CS, then I think I can make him into something awesome, but you're free to add, remove, or shoot down this idea entirely. Of course, I'm always open for other things, if you have something else in mind.
