The Tower of Heaven.
The tower was just like its name, a giant tower connecting heaven and earth. The mythical alchemy tower was the space tower and the hub of Fhartasil's Fairyland; its master was the Arcane Kingdom's Emperor, Wendy.
The insides of the tower didn't even have any stairways. The space within interspersed and tangled in a complex manner. Layer after layer overlapped upwards, like an infinite cycle that bolted up to the clouds and sky, and at last, landed inside the half-bitwall.
Numerous cities and villages were built around the tower. It was the center of Fhartasil's Fairyland, since one could see the place from anywhere by simply looking up.
Clouds surrounded the middle of the huge tower, which was like a giant pillar supporting the world. Anyone who saw it would be dazzled.
