Killian Jones wrote: recently found concept art of the doors inside the Hat :) The door next to the Looking Glass in the concept art looks like it could be some kind of steampunk world.

The light blue door with the metallic oval mechanism on the front could be Atlantis from Atlantis: The Lost Empire as it looks similar to the energy produced by the Heart of Atlantis and the metal is reminiscent of some of the architecture and technology.

The golden door could possibly be 19th Century France. However, it could also be an 18th Century Russian-inspired world as the colour and patterns are reminiscent of the famous Amber Room, gifted to the Russian Tsar by the Prussian King in 1716.
