I created this map of Lovecraft's Dreamlands for the story "Jangling the Silver Keys" in the anthology Kill Those Damn Cats - Cats of Ulthar Lovecraftian Anthology. As I reread the various stories of what is called the Dream Cycle, Lovecraft's various Dreamlands stories, I noticed that all the maps that have been made were wrong! Apparently the mapmakers either just pulled names from the stories or didn't bother to read them very well, unable to properly place cities as located by Lovecraft himself in the works; or they just don't know which way west is when the story says "west of Ulthar" for example.
The below map has all the extra places I added circled in red, because otherwise the map was very empty.
And you can check out Kill Those Damn Cats - Cats of Ulthar Lovecraftian Anthology at Amazon, available in paperback or eBook formats.
