I've always liked the keys leading to something having to do with the origin of Wesen myself, though I would want to know how exactly that could help the Seven Royal Families rule the world. However, with the Black Claw, the origin of Wesen idea would fit in well with that current storyline, so I definitely think that prediction could end up being accurate.

Looking at what Renard told Nick some of the things it might lead to, my guess would be the nails used to crucify Jesus along with pieces of the cross, but I actually don't think it will end up being any of the things he said were rumored to be the "treasure" the keys lead to back in Season 1.

Here's my official prediction, which I would say only has a 1% chance of being right, but I'll go with it anyways! I think the keys lead to some kind of weapon (think something along the lines of like an ancient nuclear weapon) that is actually so destructive that it could destroy the world--and if something like that ever fell into the hands of the Royal Families, that would in turn actually give them all the leverage they'd need for a world takeover. I could see the Seven Knights looking at an object like that and deciding something that's potentially that destructive is better off never being found again by anyone.
