Vyllurian is an ocean planet orbiting Helyar. Home of the Kya, this planet has a long and difficult history. There are two main forces that shaped Vyllurian's path—the fact that the entirety of its surface is submerged and the fact that it was only the second planet in the system to develop. Today, twenty billion call Vyllurian home, most of which reside on the more shallow polar regions. The equator is desolate by comparison, so far from the sea floor that it is devoid of nutrients. In effect, Vyllurian does have an analog to the oceans found on other planets.

While history began on Vyllurian millennia before contact with outside civilization, contact with the Triumvirate Civilization fundamentally changed the direction it was going in. Vyllurian's sister, Aegyn de facto homeworld of the Humans, consistently received more attention from the international community. For most of history, this left Vyllurian a comparative back-water, but the Sedrua-Triumvirate War was the chance the Kya needed to shine. They devoted their entire industrial capacity to fighting Sedrua and traitorous forces on Aegyn. Vyllurian rode the post war boom toward prominence on the galactic stage.

Vyllurian remained a powerful world even after the collapse of the Triumvirate. As Aegyn waged its wars, Vyllurian peacefully extended its influence. Its population was the highest around Helyar by 8800 after Aegyn was largely abandoned.
