Here's a question. How exactly does one rise through the ranks of the GK whilst being stuck in the warp? Would not the constant battle for survival in a realm of pure madness make it a little difficult to co-ordinate anything? How do the other GKs even know he's still alive in there?
The whole story is just full of holes in you ask me.
