Ok, a little backstory first: The Emperor is initially the keeper of the Sphere, tasked with ensuring that it stays stable and protected. But due to some unknown reasons (most probably Bolo trying to corrupt him) he loses his connection to the Sphere and both of them disappear to unknown places. The Sphere always needs a keeper otherwise it will grow unstable and break apart.

Which is why the agents of the Three Arrows set out to search for a person who might be able to fulfil this role. He/She is the "chosen one" of the Shadow Sphere, and would have a special affinity towards it.
