Overcome nature

There were trillions inside the Virtual Dream Universe right now. Although the relationship between the Justice Primarchs and the Neo-Demon Race grew tense over the last centuries, everyone from the most common talent to the great geniuses enjoyed the advantages of Legacy. 

Universe Dream, the one in charge of keeping the Virtual Dream Universe running smoothly, did not neglect his job just because Venganza no longer cared about the rise of new geniuses. He followed Zatiel's guidelines, which contained how to handle the changes in Legacy as the Virtual Dream Path of Power advanced through the Ranks. 

Of course, Legacy was not the only thing growing more potent now, as Eternal Nightmare also saw its laws and forces growing more powerful and stabler.

There were two main reasons why Vengaza chose to use Avernus' soul and vitality to assist him in the growth of his Virtual Dream Universe.
