Bab 1550: Awe Of Supreme Laws.

It was with this thought that he left smugly. Many world fragments could be seen floating around in the void. They have become free now that their wielders are dead. 

But he didn't bother to take the various world fragments floating around in the void because they are not ownerless. They have owners, so he wouldn't be able to use them even if he took them. This is because no one will be able to use a world fragment without the permission of the world god who made it. 

So even if the wielder dies, it is useless to take it unless you want to ransom it. Even then, the world god can take back his world fragment at any time and across any distance. Only another world god can prevent it from leaving, but no one else can use it without the permission of the world god. Not even another world god.
