I was lucky enough to stumble onto a travel guide to the land of Kymaerica here at the archives. It was being given away, and Anna, the archivist here, decided to pick it up. How fortuitous; I would never have been aware of this interesting land otherwise.
Though the book says there have been six of these guides published, the one I'm looking at is the first one to have been published in our linear universe. It led me to
www.kcymaerxthaere.com, where I learned about this parallel universe that intersects with our own at certain junctures in time and space.
Several of those junctures are marked by plaques in the gwomes Aywatin and Raalberdus in the district nMichigan (the n is silent); I hope to have a chance to see them next time I'm there!
