Wuhu Island

From Miikipedia

Wuhu Island is a small tropical island in Mushroom World (See Super Mario Wiki). It has a long and rich history, beginning many years ago.

History of Wuhu Island

Wuhu Island was formed millennia ago when volcanic activity raged under the ocean off the coast of Sarasaland. When the lava finally cooled, it had created an island a few square miles across. At some point, two groups of people, possibly related to the humans that now inhabit the Mushroom Kingdom arrived by boat, settling the island. On the north side settled an incredibly advanced civilization. Within a few years, they had built vast citadels on the cliffs there. No one knows how they got the bricks there, or how they built them to fit so closely. But they did it, and controlled the island for centuries... until the arrival of the second tribe that is.

A large group of neolithic men found the southern island, and colonized it. They built huge, yet crude, monoliths all over the southern shores. These they dragged to the places where they thought the "Great Spirits" resided; the forest, the cliffs, and even in the volcano! But it didn't last. The more advanced civilization, finding them crude savages, destroyed them and all that they had, forcing them to flee.
