When it was done, the chains released Nora, and she sagged down to the ground, now looking much the same as Elora had when Nora entered the room.
Elora smirked victoriously at Erik and declared her victory, "Just like that, we gain a pretty little thing to have fun with and a spy in the Silver Enclave, all at once. Without breaking your precious rules about consent, too. Not bad for a night's work, don't you think?"
Naturally, the questions about morality and consent were very subjective and borderline in this case, mainly because Nora barely had any idea what she agreed to. But ultimately, the world was built on compromises and the blurred lines between right and wrong.
They needed a spy in the Silver Enclave, and Nora presented herself as a very viable option. The added pleasurable benefits were just icing on the cake.
