For some time you served Nightmere, once you almost killed a monster that was supposed to harm him mentally, Nightmere stopped you, killed the monster himself, then he moved you to his castle, one of his tentacles grabbed you, wrapping around your body, he was angry, now instead of causing someone else pain, it will be you who will suffer

Nightmare - didn't I tell you about our deal?..you harm morally..AND NOT PHYSICALLY!
