Elora: Are they somehow programmed to stay so long and then get out?
Heru: There are agreements made. In that case, it was a specific mission to try to set up an underground network and I believe it was given a set time to determine if it would work or not. This type of mission was attempted with the Dark Universes that were created after the Fall. And when it became clear that there was really no redemption possible and no opposition which could be created by sending people in, it was stopped.
Heru: They don't get out, and it is possible that there is no reclamation likely for the Beings who were created by the Fallen Creator Gods in a totally Dark Universe. It appears that there are gradations of being Fallen in terms of how Dark the Beings are. The Fallen Creator Gods who have created the completely Dark Universes would be very Fallen indeed, and their creations most likely will need to be destroyed. The Races of Beings that you were asking about earlier [i.e. the Dark ET's] were created in this Universe by compromised Creator Gods. And that is the difference.
