Here a large number of undead gathered, and then some buildings were built in the middle that even Du You couldn't see the use for. Then there was a large group of undead clustering together; this was what was called a territory.

It merely meant gathering undead, preventing other undead creatures from approaching easily; that was the meaning of occupation.
