Ah, I'm going to make the reward a ralts. I'm writing it now, 1,100 words and counting.
[EDIT]
OHOHOHOHOHOH!
I has an awesome CO-Owner idea.
So i made the pickup location turnback cave, and Bane is going towards the final room. You know how the distortion world is the 'support' world for the real world? and how Giratina is the distortion world's guardian? What if the intorduction of the synthetics had a severe impact on the distortion world, causing disturbances? Such as the entrance to the distortion world in Turnback cave opening up? I won't bring Giratina in or anything, but I'm going to have Bane notice the purple glowy vortex thingy.
Oh, and one of us could even write a post from a first/third person view, referring to it only as "The Beast", or "The Dragon."
