Storyline?

Hey guys, my friend and i were thinking of a story line that is a pre-quel to the Bara Magna stuff. Remember the maze? And the cube? Well a great being was dispatched to place the cube back in the maze and re-activate the guardians. He successfully places the cube, but when he brings back the guardians, something goes wrong. They become dark and twisted, and run away from the maze towards the agori settlements. They call themselves the Skrall (This would explain why they have the mazes on their shields, and why they suddenly appear out of nowhere. What say you?
