The 5th Dimension and You (Rough idea)

This is just some more information on the 5th dimension and how it works along with your powers you draw from it. Each and every time you use your power you're drawing from the 5th dimension and tapping into its unknown supply of whatever is inside of it and using it in the way you see fit, much like how the Green Lanterns draw power from their power battery to use it inside their rings and so on. So this is the same thing and there's no way around it, all power comes from the 5th dimension and much like the power battery of the Green Lanterns the power from the 5th dimension can be cut off from anyone if need be and there's no way to turn it back on for said person; its like being turned human and being left that way.

Since the 5th dimension is its own thing, it does and takes away as it pleases whenever it wants to. You'll know when your power is about to be cut off when the sphere itself appears, but there's not much information on the topic so it's more or less a ghost story.
