Knowledge is Power

One thing Ominous was sure of is that power without knowledge was useless, and Knowledge without power to use it was just fantasy, the difference between a pantheon that knew how to create Empyrean warriors and a pantheon that didn't was like the difference between children and adults.

And the same thing applied to all other manners of power and energy, Ominous could create a soul crystal and use it to shape an Undead of his choice, he could feed the Undead with fake souls and that would guarantee a decently strong enough Undead to serve him and his minions and this was what his forces and him have been doing to strengthen there Army of undead, but now with the knowledge Drakula had given to him, he could move to a next level as a master of Death.
