Goblin is themed after the movie "Labyrinth," so the mayor (Jareth) and residents (Sarah, Toby, and Hoggle) are modeled after the characters in the film. The town has two distinct sides: the flowery, yellow/fairytale side, where Sarah and Toby live, and the Labyrinth itself, where Jareth and Hoggle live. The two sides are joined by the clearing in which Sarah eats the drugged peach, and the Bog of Eternal Stench. It is set in October (yellowy trees).
AHS is themed after "American Horror Story" (the first 4 seasons). The mayor is Fiona, and the residents are Pepper, Lana, and Violet. Each of their houses is themed after locations or scenes in the show. I wanted the landscaping to look like a well-manicured suburb, rather than a typical horror town, because that's how it is in the show. Outwardly, most of the landscaping is normal and pleasant. I stuck to a red & black theme with the flowers and cherry trees, and the bushes are a combo of red hibiscus and white azalea. Oh, and the villagers are themed--their names are the same as other characters from the show (Nan, Queenie, [Dandy] Mott, etc.). It is set in the summer.
My main town is more loosely themed than those two. Its theme is Tolkien (The Hobbit and Lord of the Rings), as its name and the mayor's name are from an old LOTR computer game. The other three residents are modeled after characters from The Hobbit & LOTR. I am remodeling alll of the landscaping and most PWPs, trying to find a balance between it being a themed town, and it also feeling like me. Whereas my other towns were made for the Dream Suite, this is the town where I play and "live." I recently came up with a path idea that I'm pretty excited about! It is set in autumn (reddish leaves).
I also have fully detailed plans for more towns: one based off a video game series, one based off a classic book/movie, one in memory of my 20-year old cat, and one based off another TV series. I don't know which to do first!
