First Trading Network of the Greater Universe

All this was happening during the time Krune and the rest were working on condensing the Realm Ability. Once Heavin sent the Soul Trading Hub away, he collected all the keys it had ejected and began distributing them to the various Gods of the Kun Realm Cluster. 

Once all the realms obtained at least one Key, Soulura would be able to give them more keys through that channel whenever more Gods were birthed in their world. Moreover, if a God were to die, she was also capable of rendering the respective key useless in an instant. 

This ensured the Soul Trading Hub would never be abused. 

And as the identities of everyone in the Soul Trading Hub were protected, this layer of anonymity would make anyone wishing to invade other realms hesitate.
