Altair eyed the black heart in his hand with fixation, having carved it from out of the Chimera. It was as big as his head, charred black by poison.
"Was it necessary to leave her alive?" Reina questioned from on top of his back. She comfortably rested her head over his hair, twirling it through her fingers bored ."Won't she come after us if we leave her alive?"
"I hope she does." He devilishly answered. "I killed her entire squad, tortured her, and left her for dead. Would you be sane after that?" Reina nudged his head silently. "She'll be driven mad, becoming our shield."
"Huh?"
The Prince chuckled knowingly. " Just like how the Chimera was feasting on itself. I want Tania to be just as mad. When she wakes, her mind will be flustered by what I've done and what's happened to her. The Aros family will call her back. And if I've done my job right. She'll refuse. Tania will go rogue. And her life mission will be killing us."
So these Aura marks your real talent alongside your first skill. Altair's is a unique grade. So are most of the high-rank bloodlines. Grave of Night merely added to his aura. Turning it from a 'SS' Rank to 'SSS.'
You can usually get an idea of a person's aura from their unique skill. As for how many Aura a person can have,... it's one.
