My name is Joseph Granger. Officially, I'm what you'd call an archaeologist's assistant. But rather than dig through the ruins of our own world, my boss and I jump to parallel worlds to find arts and artifacts related to their history. Now we don’t steal anything, mind you. What we do is borrow the artifacts, take them back to our lab, and make copies while planning to return the originals. What we do after is study the copies to see how many changes could have led history down this particular road. These are what I consider my top worlds, even if my boss disagrees with me.
