The attendants moved instantly, dashing out the side doors. Within moments, they returned, dragging along a gaunt, sharp-eyed man in fine black robes. The crest of a Slave Merchant gleamed faintly on his collar. His hands were full of intricate silver tools and a scroll that shimmered with binding magic.
There was no one particular method to conduct the slavery spell; most of those who could cast it had a different ritual to do so. But one truth remained: casting the spell was not as simple as most other spells. It required a ritual. Just as Vex's Hexwitch curse, which saw her bind herself to her beloved through a curse that affected her negatively and him positively, the slave spell was too intricate to be cast without a ritual.
This was the case when Blossom was enslaved as well. The Slave Merchant, who was forced by Quinlan and Ayame to bind Blossom to him instead of being an ownerless slave, as her ex-master was brutally murdered by them, also used a ritual back then.
