Read The Giant Horse Of Oz Storyline:
The tiny kingdom of the Ozure Isles is the Kashmir or Shangri-La of Oz;perched on five islands in Lake Orizon, surrounded by high mountains in a remote
region of Munchkin Land, it has little contact with the outside world—of Oz,
that is. The beaches are not sand but gemstones; the people travel between their
islands not by boat, but by seahorse. Or they used to, before the evil witch Mombi turned her malice in the Ozure direction. After
kidnapping Queen Orin, Mombi left a fire-breathing lake monster named Quiberon
in Lake Orizon to keep the natives prisoner.[1]
Even after Mombi is vanquished, the isolated Ozurites remain oppressed.
