To the untrained eye, celestium looks like a light-weight metal alloy yet stronger than any metal known to man. Look closely, though, and you'll see intricate patterns of lines throughout its structure. Activated with Pulse, energy moves along these tiny channels, enabling phenomenal computational power at the sub-atomic level... many times more powerful than any silicon-based processor known in the real world today.
Celestium is actually a ceramic, created in magnetically-shielded kilns that generate conditions hotter and at greater pressure than the heart of the sun. Without Pulse energy, mankind could never have made these conditions, and the revolution in computing it led to.
In the Suzerain universe, celestium is an invention of the early 21st century which helped shape the future of the world. Together with the discovery of Pulse energy, it ultimately led to the Pulse War and the start of the Elements family of realms. After the fall of the Barriers, it was Pulse-powered celestium devices that finally took mankind off Earth to colonize the stars. This is where the Catalyst realms take over from Elements.
Celestium In Untamed Empires
When the Barriers divided the planet to end the Pulse War, each quadrant of the Earth developed a different relationship with the technology that existed before. In Untamed Empires celestium was seen as a tool to give empires power over each other. Of the many mysteries of the Ancients, early imperial colonists of the Setward Isles were most interested in unlocking the secrets of the celestial metal. They'd set forth from the New World in search of celestium, and with it they would return - rich as gentlemen. Gold and gems were nice, but nothing made an explorer's name more than discovering a heap of blasted old equipment from another age.
The following text comes from the notebooks of famed philosopher, social commentator and scientist Zachi Da Benecasa (Yr174 - Yr249):
''Although called a metal, an increasing number of natural philosophers agree that the substance shares many properties with the ceramics of the Pharaoh Islands as well. How can this be, many wonder, when the material is several times stronger than steel and a fraction of the weight? Stranger yet, devices constructed with celestium components just... work better. Many drowned marines will attest to the viability of nautili created before the invention of celestium-lined purification bellows.
''Star shamans and other spiritually aware individuals report sensing a faint hum like the boundless energy of far distant stars when celestium-powered devices are working nearby. This has led to many people venerating the material, and just as many refusing to go anywhere near it. With so many questions unanswered, there's no telling what that kind of power could do.
''Although a large number of ruins of the Ancients have been found underneath the ocean's surface, occasional Artifact finds can be stumbled upon throughout the islands. Rumors persist of a deposit in the mythological City of Kings that puts all other collections to shame, but that's rumor for you. If it's not mammoth quantities of the wonder material in a ruined city that no one has ever seen, it's the local governor being replaced by his evil twin brother or a proposed grog tariff.
''There are those in the Church of Trinity who support celestium use whole-heartedly, claiming the alloy to be the blood of martyred Avatars. Certain zealots have even been known to heap scorn and coarse vituperations upon those who are deemed unworthy of debasing such a blessed material. The Varlinian Soke certainly collects a lot of Artifacts, which disappear into the endless vaults under Napri with relatively few Celestium-imbued items coming out. What happens to the rest, nobody knows for sure. Except for the Patriarch, and he says nothing on the subject.''
