Warhammer 40k: G'mork and his Army

My first task was to write out the lore of how G'mork obtained an army.  It was agreed upon that G'mork received his power from Warp, an alternate reality that allows FTL travel but is also infested with demons.  While traveling too close to a Warp storm, G'mork was captured by a demon, tortured, and infected with a rot.  However, this rot mutates him, allowing him to infect others via spores.  He escapes on a demonic ship (like the one pictured below), and goes on to try and obtain an army.  You can read my contributions to G'mork's story below.

G’mork had successfully escaped the Eye of Terror, with new found abilities and a small army in tow.  However, he was quickly intercepted by an Ork ship that had wandered too close to the Warp rift.  The Orks were drawn to it, seeing it as a relief to their boredom rather than a trap waiting to be sprung.  Nurgle’s ship looked more like a decaying corpse of some giant animal than something that was space worthy, so the Orks thought of it as an easy victory.  

Boarding the ship was no easy task, as most of the hatches seemed to be grown over by some greenish, rotting material.  A pungent, swamp-like odor hung in the silent air as the orks explored the corridors; with the only light coming from luminescent mushroom bulbs that glowed a dim, sickly yellow.  Undeterred by this, the Ork pushed forward, delving deeper, and deeper into the ship.  At the back of the party, one Ork peered into a small crevasse, and noticed a body shoved awkwardly in the crack.  He tapped the corpse with an axe, to make sure it was dead.  But at the slightest touch, the body burst open and sprayed him with bloody mist.  He stumbled back, but quickly found his footing.  After burying his axe in the corpse for spraying him, he rejoined the party.  

A thought began to take form at the back of this ork’s mind, an insistent, irritating thought.  A name began to surface, G’mork.  All at once, the holy spirit of Gork and Mork came upon him; and a grand vision of a Great Waaagh! flooded his head.  If orks could cry, he would certainly have been brought to tears.  It was at this moment that he knew what his purpose was, now he just needed to share it.  He grabbed the ork nearest to him, and took a deep breath in.
