Abdicate power for even a second, and nothing would ever be the same again. Everything seemed to be the same as it ever was, but appearances were deceiving. He had been confined to a pocket universe.

By the time he realized what had happened, he was no longer able to find her domain. Only ever smaller copies of it.
