Unlike normal Coercion, it couldn’t be fought off with mental shields or any spell I knew. It was as binding as a death vow and that made it terrifying. It took a soul sacrifice to achieve such high levels of dark magic. If your soul wasn’t intact when you died, it could forfeit your place among the stars, they could cast you into eternal damnation and suffering. And nothing that happened in this life was worth being cursed for eternity by our celestial rulers.
