There are three such Gates, at the top of each of the greatest towers in the world. The Heart of Light, crackling with holy power and eternally shining with blinding light, it is the center around which Ravi Shahar has been built, the greatest city in the known world, a place of everlasting day. A Witness of the Light is granted powers over light and darkness, metal, and even lightning.
The Fist of the Flame, the second Gate, eternally burning and roaring with a deafening flame, burns above Stahlturm. The walls of the tower are reinforced and thickened, and many layers of padding have been added by most residents to drown out the roar of the flaming god. A Witness of the Flame is given command of fire and ice, sound and movement.
The third and final Gate, the Maw of Shadows, the gate of crushing darkness, rests above Kagenoyama, burning its curse into the entire area. A Witness of the Dark is given dark powers over decay, weight, and curses themselves, but is certainly doomed to be cursed themselves, and to become like the twisted denizens of the swamp around the mountain.
No one knows where the Towers came from, or who built them. They have existed since long before men, and truly no one can understand the artifacts and demons that reside within them. Many of these artifacts are wonderful tools, like the Sacred Pools or the Eyes of Journey. Some are deadly weapons, like the Rods of Hatred, which twist anything targetted until it shatters into countless shards. But whatever must have built these towers, and these tools, must bee soon to return, surely?
