Celestial Gearworks

The Celestial Gearworks is a truly ancient bastion of order and law in the universe, so much so that it stands completed and active even in Mortan's earliest memories. It keeps consistent time across all worlds, and axles protruding from the Gearworks regulate all orbital structures such as planets and satellites. The surface of the structure is safe enough to walk upon, meaning in theory that it is possible to walk from any planet to any other planet, given enough time.

The Gearworks emits light approximately equivalent to the umbra of a solar eclipse: Definitely bright, and probably unwise to look directly at, but not nearly as bright as an actual Sun. However, most planets are treated as being in daytime when facing the Gearworks, and as being in nighttime when facing the Great Beyond. There is further an amount of waste heat emitted from the friction of the gears, which reinforces the warmth of daytime upon worlds facing it.

Finally, the Celestial Gearworks embodies a force of metaphysical law. While the surface of the Gearworks is safe to stand upon, attempting to penetrate the deeper layers of the structure eventually will result in a gradual slowing of motion as any form of change becomes more and more difficult, until finally all change ceases and the unfortunate spelunker is trapped in stasis for eternity. It also is known to keep the seemingly unlimited strength of the Great Beyond at bay as long as it continues to turn, which is a vital function for the continuation of existence in the Universe.

At least according to Mortan's memories, the Celestial Gearworks is historically associated with the Titan Legis, sometimes known as the Ultimus of Order.
