Also, Seth made Grimm the End and it's his favourite? He deliberately made his own future vessel? It's possible he's made all of them for the purpose of becoming future vessels and chose to reside in his favorite when the Original Sin was split. We know he made the sword and that glass is pretty resilient for how many times it's been dropped and not even cracked.

Maybe there's only one that's a legit magic tool minus the demon, but maybe Seth used science to engineer the ideal vessels for himself and the other kin in Sin (if they're the demons, which I think get elluded to later on).
