An Expansive Domain
He wasn't the only one stunned at the scene.
Even Alice was.
'She's a Grand Sorceress of Adam. She inherits the perfect foundation of the human; it's an Expansive Domain!' Alice was in shock after recognizing the ability she was using and this woman.
She was basically her counterpart in the human race. Just as Vampires have Heirs who Inherit Ancestral Blood, humans also have and are spread out among the Three Alignments of the Human Empire.
They are people who inherit Ancestral Blood, and while they are not necessarily descendants of the Human God of the past, the blood they carry is so amazing that it grants them powerful abilities as the Heirs.
There is a clear difference between the abilities that the vampire heirs receive and those that the Humans receive, with the vampires being the most powerful. However, no one among them has an inherited ability like that right now.
