==Iscarynn Ronin== 
As the Thirteenth Crusade stretched on, the forces of the Unyielding Vigil launched a devastating assault upon Imperial Eldar space, hoping to cleave through the faithless xeno and encircle the Chaos Legions rampaging through the upper Segmentum. The first to feel the brunt of this offensive were the Corsair Princedoms at the edge of Imperial territory. Many worlds were abandoned as the Eldar made a fighting retreat, but some territories were struck harder, such as those of Prince Uledainn. The Prince's flagship was destroyed in the fighting and his fleet scattered, his Princedom falling into chaos. As the tides turned and the Eldar began to push back, the scattered elements of his fleet returned with new masters to reclaim Uledainn's worlds, but the Eldar underestimated the indigenous populations' loyalty to their former master. The Princedoms played fast and loose with the laws of the Empire, and many human Custodian Worlds within Uledainn's domain were bound to the deceased Prince not only by veneration, but by a sense of mutual respect.

Disgusted by the sight of their celestial lords bickering over Uledainn's holdings, the world of Iscarynn declared itself ronin, pledging that if they could no longer serve their former Prince, their only master would be fortune. Successfully fighting off the small, hastily-assembled force sent to reclaim it, the planet has since settled into a state of truce with its neighbours, and has become valued for the quality of its warriors, few Princedoms wishing to risk losing such an asset in an attempt to take the world for their own.

Since then, the Iscarans have fought on battlefields across the Segmentum and for a multitude of employers. Specializing in mobile warfare, they utilize large numbers of Stinger (simplified versions of the Eldar Wasp walker design, dumbed down for use by Custodian World humans) squadrons to great effect, engaging in perilous skydrop maneuvers to outflank their marks.
