Alrighty.  I can do that :D

As for the first world I still like the idea of our first world be something of a nexus.  Maybe a town surrounded by a random warping field so there are things from everywhere.  Maybe, in this world, we'll get our device after doing something for a group of mutliverse travellers? 

I kind of figured we'd go through the worlds as ourselves, but I'm open to something different.
