Druuvai are a race of spirits carried to the planet of Baeriia on the trail of the Comet Caarvelian, locked into an extremely erratic orbital path around the plane. It returns every 30-200 years, showering the planet with a rain of stardust, and a deadly, flesh-eating parasitic entity referred to as The Rain. 2,365 years ago, a piece broke away from the comet, and slammed into Baeriia. It dug deep into the earth, and struck a vein of vibrant garnet. A fragment of that garnet then began to absorb the stardust carried on the comet. It incubated for nearly 2 years, before being found by researchers. By that time, the surrounding area had become thick with a stardust-heavy fog, glimmering like a nebula. And at that nebula's heart, sat the shard of garnet, now fully enveloped by the first creature known as a Druuvai. The stardust inside of the nebula had condensed around the gemstone, the magic of the planet giving it shape and sentience, and eventually, it became Ekhart... the first Vai. The researchers took him in and cared for him, for years as he grew. Then, fourty years later, the comet passed by again. With potent magic, an enormous wash of blue flame illuminated the entire sky in an event known as the Searing, creating a protective barrier around Baeriia, keeping out the Rain.
More druuvai arrive
As the comet shed stardust again upon Baeriia, people from around the world gathered at the original star nursery. They threw anything from common rocks to prized family gemstones into it. As those stones entered the nebula, stardust gathered and more druuvai incubated. The first generation of vai. These first generation vai became the founders of vai society. They were spirits, made of pure stardust, come to protect the world. The first 5 druuvai were known as the Architects. The next 20 became the Firstborn. Following the first 26 vai's emergence, the nebula exhausted, and future generations would be sculpted by their hands (see: Reproduction).
Ghosts and reincarnation
Baeriia had a unique problem. The god of this world was a mere 12 year old boy, called the Creator. The Creator could make new souls, but could not control their path beyond that. When mortals died, their souls became ghosts, drifting in the uncertainty of reincarnation. They would either move to Hell, where they became demons for eternity, until killed once more. Or, they would reincarnate. If a druuvai killed a ghost or a demon, their soul would instantly return to the cycle of reincarnation. Hence, they became tasked with keeping the balance between mortal, demon, and ghost. As their bodies were comprised of magic, stardust, and earth, they were golems. Without a soul to be stolen into Hell.
