The Clockwork Nirvana of Mechanus
On Mechanus, law is reflected in a realm of clockwork gears, all interlocked and turning according to their measure. The cogs seem to be engaged in a calculation so vast that no deity can fathom its purpose. Mechanus embodies absolute order, and its influence can be felt on those who spend time here.
Modrons are the primary inhabitants of Mechanus. The plane is also home to the creator of the modrons: a godlike being called Primus.
Mechanus is a great void filled with unimaginably huge wheels, each interlocking with the next, like the internal cogs of an ornate clock. The plane is filled with thousands of these clockwork disks, the largest having a diameter of more than 1,000 miles. The slow revolution of this titanic wheel is picked up by adjacent cogs and transferred to others throughout Mechanus, setting the entire plane in motion.
Both surfaces of each circular realm have their own gravity, so disks can meet at right angles without disturbing the inhabitants of either one, and creatures on opposite surfaces of the same disk are drawn to the surface by their own gravity. The void between wheels contains breathable air. Mechanus is a plane of ultimate law, the very antithesis of the Elemental Chaos and every bit as alien to mortal minds as the Far Realm. Light and dark exist here in equal measure, as do heat and cold. All matter here has its place, where it remains irrevocably. Mechanus harbors no passion, illusion, or pain. Individual consciousness is temporary, serving only while needed and then subsumed into the whole.
Regulus
Sixty-four interlinking cogs at the heart of Mechanus form the metropolis of Regulus. The cogs of the modron capital rest atop each other, like a colossal, mechanical ziggurat. An enormous rod runs through the center of each sector gear and is apparently the agent of rotation. Each sector is ruled by an octon and periodically inspected by a septon, which in turn reports to a hexton, and so on, until the report reaches a quarton regional governor. Deep in the heart of the modron metropolis is the government sector, Regulus Prime. There stands the Cathedral of Order and the Tower of Primus, demesne of the supreme one.Modron Cathedral
This towering edifice seemingly defies all natural laws—it’s much too slender for its height, and its interior is far vaster than its exterior suggests. Inside, stone walls support vaulted ceilings that spring into the sky, their upper reaches lost in shadows from below. Balconies on hundreds of floors ring the open space in the center, with thousands of modrons moving about on their errands. The central feature of the Cathedral is the Orrery, a mesmerizing latticework of gears that constantly spin and move about. Those knowledgeable in such things can recognize the Orrery as a model of the multiverse, incredibly detailed and infinitely complex.Tower of Primus
A fantastically complex clockwork fortress, the Tower of Primus is a forty-one-story structure composed of rectangular blocks, each stacked slightly askew from the previous one to form a spiral hovering within the sky over Regulus Prime. The skin of the tower shifts from black as night to bright and shiny, seemingly at the whim of its master. At the heart of the floating structure dwells the One and the Prime in its energy pool, connected to the collective through the Infinity Web
