Yunin

The Yunin are an enigmatic Xenos race, supposedly hailing from the Veiled Region, a vastly unexplored part of space at the southern border of Segmentum Tempestus. Encounters with representatives of this species have been reported since the 32nd Millennium, but the first confirmed contact occurred in 405.M34 by Inquisitor Kormann.

The details of this meeting are not accessible by the public, but little changed afterwards and so little is known about them that their existence is not recognized by most officials. The most common form of interaction between the Imperium and members of this race is conducted by Rogue Traders who sail the Veiled Region and occasionally return with vast amounts of Xeno-Tech.

The Veiled Region
At the southern border of Segmentum Tempestus lies a part of space full with dense nebulae and plagued with the radiation of newborn stars. Stellar dust and matter obscure this region of space and make scans nearly impossible. From the early days of the Imperium on, the Veiled Region has remained unexplored, as astropathic communication proves difficult at best.

Weapons
After Inquisitor Kormann confirmed the Yunin's existence, masses of Rogue Traders and smugglers flocked to the Veiled Region in order to establish trade with the Xeno race. Those lucky enough to successfully navigate through the clusters would later return with their cargo bays full of Xeno artifacts and weapons. Vast amounts of these artifacts were quickly seized by the Ordo Xenos and found to be of equal or slightly higher technological standard than the Imperium. Some of the more destructive weapons however proved useless in human hands, as they were gene-coded.

Graviton Weapons
These weapons operate similarly to those of Imperial origin, manipulating gravity in the target area through the projection of graviton particles. Different from the variants used by the Imperium however, weapons recovered from the Yinun usually lighten the target's mass rather than increasing it, causing the atomic bonds to stretch until it eventually explodes or dissolves. They are also more sophisticated than Imperial variants, resulting in a smaller size and a more efficient use of energy.

Deconstructor Weapons
Among the more terrifying systems developed by the Yinun are weapons labelled Deconstructors by Imperial scholars. Varying in form and size, the ground principle is that a hollow bolt is fired at the target, propelled by magnetic acceleration. The high speed of the projectile enables it to pierce even thick armor, though the real danger lies in the agent contained with in the bolt. A strong bio-reactant, any organic matter injected with it will be subjected to rapid, erratic cell and tissue growth. Not all of these agents are lethal, with some only only disfiguring the target to a point when they are unable to move. Most of these lead to eventual organ failure, though.

Space Travel
The Yinun are capable of traversing the Warp, though their methods differ from those of the Imperium. Rather than sending a ship directly into the Immaterium, they make use of unmanned drones which are sent to a target location and then act as a beacon for long-range teleportation. Why the Yinun take this convoluted approach is unknown, though scholars suspect that they lack the capabilites of human Navigators.
