I apologize, I have little time to respond but wanted to none the less. Eleon would work well in this environment, or maybe a mixture of #1 and #3. Locke to be the monarch, with Gad as the human participant in the arena. I'm fully prepared for this to be a multi-chara Nation RPG. I have ideas how to intermix #'s 1 and 3 to be cohesive with your own. Gad would also take the the title as "Runner" stated in the middle paragraph of #3. I'd have to take a day or so to rewrite the two ideas into one. But, as you say, if this doesn't work it still has potential to lead to something else. 

I'd love to hear your ideas for any of the four listed in my first post. I'm dying for new things to write.
