Someone speaks words of sorcery and dismissal, a harsh combination of the language of magic and the language Infernal; and the slimy devil that wrapped around Carissa is gone.
Abrogail takes the Splendour headband from Carissa's hands, and turns it, marveling at the craftsmanship. There are, perhaps, a few eighth-circle casters in the world, who could produce craft on this level. Abrogail Thrune herself is not among them.
"You're done," Abrogail murmurs to Carissa, as she gathers the very strong fragile thing into her own arms, "well done, very well done, rest now. Your aura is stronger. When you've rested, we'll see if you've reached fifth-circle from this."
She'd planned to push Carissa further than this, it is not clear from the strength of Carissa's aura whether she's reached fifth-circle or not, definitely not sixth. But other events - which Carissa is not at all ready to hear about - have necessitated cutting this experiment short.
