Seditioner's Amulet

The Seditioner's Amulet is a a sort of artifact which allows the entrapment of souls, as a soul gem that may or may not be re-used (the well known aspect of Azura's Star), but also summon a Daedric Prince for an audience, one that Boethiah is slightly more likely to deign to answer.

It currently has The Dragonborn's soul.
