Ok, ok. So it *was* the Taiidan:
The Taiidan have risen under a new leader, the Vaygr warlord named Makaan. He calls himself the Sajuuk-khar, the chosen one; many systems have already fallen under his shadow, and his eyes are set upon Hiigara.
The Vaygr are a warrior clan originally from Vay, an isolated planet in the Eastern Fringes of the galaxy. The discovery of early and inefficient hyperdrives enabled these warriors to travel and raid widely across their sector of space. Always a nomadic race, the strongest warlords brought groups of Vaygr together into crusades. A Vaygr crusade is entirely independent - the build capacity of their Motherships combined with the resource harvesting abilities of their individual craft enable them to live self sufficiently in space. Communication between separate crusades is minimal.
Since that time, the Vaygr have integrated many separate races, civilizations and technologies. The planet Vay is lost in the sands of time, the name they take its only living reminder. Constant infighting between separate crusades and jockeying for position among warlords has kept the Eastern Fringe a warzone for as long as any can remember, and therefore no threat to the larger galactic civilizations.
Until now. Under the guidance of the Warlord Makaan, the various tribes of the Vaygr Reaches have formed into a cohesive force. While still operating independently, the overall strategic aims of the Vaygr have been coordinated and focused by Makaan, a master strategist.
Their recent acquisition of a long jump-capable Hyperspace Core has allowed the Vaygr to stage raids into the hearts of enemy territories, while their nomadic lifestyle and mining technology give them a speed and mobility unmatched by any of their opponents.
More a Messiah than Warlord, Makaan has been hailed as the Sajuuk'Khem, the Manipulator of He Whose Hand Shapes What Is, and his people the Sajuuk Khar, The Chosen of God.
As a people, the Vaygr are unrelenting and persistent in combat. Space holds no fear for them, as much of the civilization has never lived planetside. Massive roaming fleets drift through the Vaygr Reaches, stripping minerals and supplies from asteroids and passing comets. Nomads, they have no concept of home, merely lands open to pillage.
Under Makaans rule, they have spread far and wide. None who have stood against the Vaygr have managed to hold them back. The devices they use to strip planets of their mineral wealth leave bare husks of worlds behind. In order to expand, the Vaygr have no choice but to press ever onwards, crushing worlds anew as they do so. Given time, they will have strip mined every habitable planet in the Galaxy.
Utilizing local Hyperspace Gates and high speed Transport Frigates to reach the front line, the Vaygr constitute a high speed, flexible war force. Individual tribal captains lead the battle from the front lines, organizing and coordinating attacks even as they come under fire. Each Vaygr craft is a highly specialized unit, designed to fulfill a single task with lethal efficiency.
Even the vaunted Dark Fleet of the Vasarii have succumed to these predatory zealots!
