'Territory.' This was a unique space that only answered to one individual — right down to the Laws this space adhered to and was operated by. Normal spaces adhered to all the ordained natural Laws that had, so far, kept its realm afloat. However, Territories only answered to the Law laid down by its Demigod owner.
This was the most important reason why people at the peak level of power were called Demigods. They possessed the ability to form their own Laws, something that was supposed to be exclusive to divine beings.
For example: in the Demigod Lich's Territory, he could summon an endless amount of undead, and control the actions of every one of them. This arbitrary control over a near-infinite amount of lifeless beings violated the normal Laws of reality.
