ooh okay, I got it... what about somewhat of a mixture of the two? So, my character [i]was[/i] the vampire king (or a prince or something, perhaps, if not -the- king), and was captured. But, rather than kill him, the king of Nillumin decided to bind him and make him a servant as a statement, a gesture of absolute control. And then we can go from there- my character no doubt plotting his bid for freedom, and yours... perhaps plotting the death of his father and an end to the war? Idk. So, it would sort of start with the first plot, and potentially lead into the second one.

Or, if you would prefer to keep it just to one or the other, that would be fine. I'm just greedy and I like both lol.
