Dahlia didn't need a prophet to tell her that she was in Azala's coven. For her to have defeated Aurelia - although under distress- she had to be powerful enough. And just as Dahlia thought, she owned her own coven.
Dahlia could tell by the respect showered upon Aurelia that she was the leader. Moreover, none of them could look her in the eyes and it wasn't surprising that she ruled with an iron fist. She was evil incarnate.
"You're back, Mistress," A woman came into view while Dahlia fought against whatever spell Azala had on her to no avail. She couldn't move from that spot even though she imagined moving her body mentally.
"And you're right on time, Hecate." Azala told her, "Quick, prepare the warlocks for the mating. Before the other sisters arrived, I want to be the first to have laid claim and began the breeding already."
