Ivory

"'Ivory is the energy that enables all of our technology and electricity. It was bestowed upon us by Him to let us lead lives of comfort.' - Yon"

Ivory, in its pure, extracted form is a white liquid. It is the essence that all matter native to the Planet are made out of. Notably, this implies that anything not made of Ivory is not of the planet originally. Completely extracting all Ivory from an Ivory-based substance or object reduces it to Detritus Dust. Ivory is also the main source of power for the human societies of the planet. The One Concern, and to a lesser extent the Isi, mine Ivory from the planet to power everything from machines to electricity to weapons. It is considered sacred to the Tri religion, and may not be touched by commoners. It is also used in the ritual of Transcendence. Transcendents, having been fused with Ivory, become able to control it after transcending, granting them supernatural powers over the world around them.

=Use= Because everything of the planet consists of Ivory, it can be extracted from nearly anything. The One Concern usually mine it from the planet, or from one of its two moons, then conver it to Ivory Batteries for practical use. This fuel is used to power everything from machinery, rocket fuel, and weapons to day-to-day conveniences in the home. Only Mechanics and Engineers blessed by the One Concern may touch Ivory. Commoners may only touch Ivory Batteries, which are provided to them by the One Concern Progenarians. The Isi also mine Ivory for their lives and machines, though their technology and extraction methods are far more primitive.

=Overmining= The planet is running dangerously low on Ivory. When it began to run out, the One Concern started mining the large moon instead. After mining it nearly clean, the moon started to crumble as it started to deteriorate into Detritus. The planet itself is dangerously close to reaching the same fate.

=Controlling Ivory=

Mediums
Mediums are blessed with an ability to control Ivory. As the entire planet is made of Ivory, they have limited control over the planet itself. Royal demonstrates this by growing square flowers from the ground in the Shard Wastelands. This also gives him the ability to strike Ivory machinery and to open mechanical doors, which are powered by Ivory, as well as many other similar abilities.

Eyes
Eyes, while not made of Ivory themselves, have the ability to control Ivory machinery. They can take over and possess anything made of Ivory, including Transcendents. Eyes are the cranks that turn the machine Planet's metaphorical gears and cogs. The Eyes operate Spine Controllers to manipulate Planet Spines, which in turn control the Abstract Cubes that make up the planet. By this means, the Eyes can control the entire planet.

Concern Controllers
Concern Controllers are devices made by harnessing Eyes. They have similar capabilities, but are under the One Concern's control. The technology is not fully developed, and they are not capable of controlling Ivory equipment as well as Eyes are.

=Things not Containing Ivory= Because everything native to the planet is made of Ivory, anything not containing Ivory is implied to be foreign to the planet. Notable examples are:
 * Eyes, which are not made of Ivory but exist to control the planet.
 * Humans, other than the Transcendent, which arrived on the planet on Ancestral Vessels in times long past.
 * Isi Seeds, which were also brought to the planet aboard the Isi's Ancestral Vessel.
