Inside the Cerulean Galaxy were vast amounts of worlds numbering in the billions, but few of them had the required resources that Rowan wanted.
Aether could be found in every corner of the universe, but it was not distributed evenly. For the planets that were lucky or some would say unlucky to have a suitable amount of Aether in their vicinity, changes would begin to develop on these planets, giving the world a consciousness and creating various mystical resources.
These resources included magical metals like Davross, Adamantite, Silverine, and many others. There were also magical plants, locations, and most importantly, an indigenous population that had potential and was in sufficient numbers to feed him a vast amount of Soul Points when they died of natural causes, or due to war and sickness.
