Hokkaido, formerly known as Ezo, Yezo, Yeso, or Yesso, is the second largest island of Japan. It also hides the Third Vertex.
After the final Pillar was placed at the Sixth Vertex, the Third Vertex beneath Hokkaido activated once again. This time, as the beam of light it emitted struck the Earth's iron core, it was accompanied by the light beam ignited from the other five Vertices, causing a series of harmonic waves that repelled the Dark Sun.
The Third VertexEdit
The Third Corner of the Machine, the Fire Maze, is located beneath Table Mountain. Like every other Vertex, there is the inverted pyramid of the Machine, which is set above a seemingly bottomless chasm. The inverted pyramid itself can only be reached by a river of lava from a kind of dock using boats made out of an unknown stone that doesn't melt into the magma, and whoever places the Pillar is expected to fall off the end of the bridge and into the abyss.
Throughout the Vertex is a maze suspended over a lake of molten magma stretching all the way to the entrance, and the creators of the Machine built bridges out of the same unmelting stone. These bridges are set in rows of three with only one safe bridge extending to the cavern containing the Pillar, and the safe route was transcribed onto the plaque describing each Vertex.
During the 13th century, the Japanese Shogun, already pocessing the Third Pillar, had an elaborate trap built within the maze to contain the Pillar until someone worthy came to place it.
