Korben has been running his various shops for as long as anyone can remember. Korben's Curiosities. Most of the storefronts are run by talking crows rather than Korben himself, but he seems to have memory of each and every one of those transactions, either pointing towards some magical trickery or a tightly interwoven web of information between each of his storefronts.

If you need something, whether or not you know it, Korben has it. You just have to come looking for it.
