Much like what was done for Not Gods But Monsters, a part of the pre-writing process was spent creating a visual representation of the world.
Maps of Tah'afajien
As a part of the world-building process that went into laying down the proper groundwork for a multiple-volume book series set in a believable world, I created a maps of the major cities/villages and topographical features for Not Gods But Monsters and its future sequels. This allows for believable references to locales that the story might not take the reader until later books.
