I tried to graze the other subs to see how they connected but didn't hit on a key. Is there something the owner does to activate these different powers? Quests or judgements he has to do for them to light up? I also didn't know what other items were meant "the others" as far as knowing when they were betrayed and losing powers. Seems that would be a good spot to itemize the items that were connected...or explain how the king links items with the ring if that is how it works.
Great description with an excellent background. I can see the Red Duke working his selfless act wishing to all that he could take the misery of all those upon himself. The knife, joining his mission and answering his call, slowly being inbued with the power. Its permanance then solidified in cloud of shadow wrapping the knife at the same time the Red Duke uttered a final agonized scream of triumph for the good he did.
Looks like a nice gift for an ugly, deformed chick. Anybody else is screwed!
Can it not be destroyed? Seems like at some point somebody would burn it or it would destroyed during the "capture" since the aim of the lust is the person wearing it, they wouldn't even notice the clothes they were shredding.
