A World of Fantasy Worlds

One day I was wondering, what if all of the famous fantasy worlds co-existed as one universe? What would that look like? I chose seven popular worlds from fantasy novels and researched what I could about their geography. Below I included my notes about why I chose to design the map the way that I did. Let me know your thoughts or share your own!

Oz was intended to be a real place and is located somewhere on the planet Earth that can never found. Oz is secluded from the rest of the planet and it completely surrounded by desert. This isolation protects its inhabitants from invasion.
Narnia is its own continent bordered by the Western Sea. Is a continent all on its own. On the other side, was the Western sea that and unexplored Western Islands (which are our other magical worlds). The world of Narnia also included Great Eastern Ocean.
This book was based on happenings in Oxford. So I made the land represented as England. 
The exact situation of Neverland is ambiguous. The name for the real world is the “Mainland”, which perhaps means that Neverland is an island located slightly away from the Mainland (Britain).
Middle Earth 
Middle Earth is the central continent of world, which is bordered by the Great Sea Belegaer (analogous to the Atlantic Ocean). An uninhabited Eastern continent is also mentioned (but really it is all these other magical lands).
Hundred Acre Wood
Hundred Acre Wood is a representation of the Five Hundred Acre Wood in Ashdown Forest in East Sussex, England.
In the novels, Hogwarts is somewhere in Scotland, but it invisible to Muggles (non-magical folk). 

Comparisons to our Real World: 
In my eyes, Narnia is based on Australia… if it was trapped in an eternal winter. I think the similarity comes from the rolling hills and mountains thick with forests and the beautiful seas and lakes.
I always thought Oz was comparable to Africa, hence the shape I’ve drawn on the map. But I have read that Oz is very similar to the United States, with the Emerald City being inspired by Chicago. There is mixed forest and farmland in the East, treeless plains and fields of wheat in the West, and warmth, lush growth, and red earth in the South.
Middle Earth is a mix of England and New Zealand. This one’s pretty self-explanatory: JRR Tolkien drew inspiration from the English landscape, but the films were set in New Zealand.
Again, very self explanatory: Wonderland/100 acre wood are compared to England.
For me, Neverland is very similar to Iceland. As I said, the name for the real world is the Mainland, which suggests Neverland is a small island – like Iceland. In the book, it says Neverland is near the “stars of the milky way”. I think this is likened to the Northern Lights, which can be seen from Iceland. The small country also has stunning scenery – it’s somewhere I’d love to visit. Imagine hiring an iceland camper van and touring the island… dreamy!
Hogwarts is somewhere in Scotland in the novels, so I can’t argue with that.
Great Sea -> Atlantic Ocean
