A-Z of Non-Existent Places

My idea here is to explore making a fictional travel guide to all these places, all of which are fictional and most of which are horribly dangerous. I think this is a pretty strong idea as I've got a couple of alternative choices for each letter of the alphabet and I can probably make something funny out of a lot of the locations, as they're primarily from comics or fantasy. I also might explore the idea of Lantern worlds from DC Comics lore, as each coloured cosmic Lantern is from a different world (Green = Oa, Orange = Okaara, Red = Ryut, etc) but the monochrome requirement of the brief would restrict some ideas I have concerning that concept, so again I may save it for a more fitting opportunity.
