'Artifacts' is the catch-all term for the stuff the Warehouse collects.What any given one does depends on the circumstances/person that made it, but canon has specifically referenced a laugh-yourself-to-death one. Basically, what I'm going for is the knowledge that the word is important and this would be an appropriate context to use it in, not anything else about them.

If it won't fly, no worries, but I figured it wouldn't hurt to ask.
