Great. The Custom planet I'm using is Espurn, a Forest World in the Calixis sector, where the primary regiment types are Recon and Light Infantry regiments, designed to be used as scouting and skirmish forces to supplement larger multi-planet forces operating in the Sector. The particular regiment is the Espurn 115th Light Infantry regiment, which had been operating on Cadia as part of a training system designed to integrate the various Guard forces in the Sector with each others tactics, to enable them to work together easier.

Name: Corporal Caius Langston

[hider=My Hider]
He is primarily armed with a Scoped Roth Pattern "Lightning" Lasgun, allowing him to fill a role of Designated Marksman, in between that of infantry and sniper, it is modified so that the scope sits above the top of the gun in a manner that still allows the integrated sights to be used. He has an Autopistol as a Sidearm, given to him by his father upon graduation of the Espurn Recon Training Program, two standard issue Frag Grenades, and a survival knife that doubles as a bayonet. Generic gear includes a Vox Caster unit, capable of reaching across the surface of most planets, and even ships in low orbit, an Auspex scanner for detecting enemies in close ranges, and a pair of Binoculars for scouting, on top of the standard issue guardsman gear for most planets. His uniform consists of camouflage fatigues with light flak plates integrated into the cloth of the uniform, and a standard Flak helmet.

Notable Deeds:
Graduated Top of his class in Espurn's Basic Training program, and was in the top squad of the Recon Training Program. He served as a Vox Operator in a scouting force during the final years of the most recent Black Crusade, one event of note is when he managed to take out a unsuspecting Cultist general from a sniping position, allowing the Chaos forces to be routed, securing victory in that portion of the battle.
Time with Inquisitor: He was only recently recruited, being pulled from a Joint-Combat Drill program with the Cadian Guard, allowing the various  planets' regiments to become accustomed to working together
Appearance: Caius has a rugged appearance, due in part of his extensive wilderness survival training as part of an Espurn recon unit. He keeps a short, but ragged beard, and scraggly, short brown hair. He's very lean, and somewhat muscular, in fair part of carrying a Vox caster on his back almost constantly. His skin is a light tan color. He is around 5 feet and 11 inches tall, with a weight of around 185 pounds.

-What are the origins of the Orks?
Thr Orks, originally known as the Krork, were created by the Old Ones as warriors capable of using any technology in the known universe, thanks to latent psychic abilities that allowed them to alter reality to fit their beliefs. The Old Ones were killed off before they could complete the design, and the Orks began to roam the galaxy, fighting any and everything they could find.
