Okay this is my second story but I scraped my first story because it was rubbish. I hope you enjoy this hopefully better story.

Cadia. Fortress world and home to the Cadian Gate, one of the only stable routes out of the Eye of Terror; Cadia is one of the most strategically important worlds in the galaxy. The Cadian Gate is the one escape route out of the Eye of Terror, and the forces of the Chaos traitor legions have launched many attacks to gain control Cadia and thus secure their entryway into the universe. The first line of defense against the legions of horrors that spit out of the warp gate is the Imperial Guard of the Cadian Shock Troopers. Millions of brave men and women stand ready to battle the armies of Chaos, sacrificing their lives to hold back the unholy armada of Chaos. One lord of Chaos has launched thirteen so-called 'Black Crusades' against the warriors of the Imperium. This Abaddon the Despoiler has been pushed back time after time; however he managed to secure most of the world of Cadia in his thirteenth Black Crusade. The warriors of Chaos established a major foothold on the fortress world, although their fleet was destroyed by the Imperial Navy, leaving them without resupply or reinforcement.

Our story begins after the defeat of the Chaos fleet, and in the tight streets of a once great Cadian city a battered regiment is mopping up the remaining Chaos forces entrenched there.

Bolter and las fire were exchanged in the streets of Kasr Kallen. Three Chaos marines of the Black Legion walked out of a nearby building accompanied by a squad of seven cult Guardsmen. Several artillery shells hit the ground in front of them, taking out two of the Marines. The startled guardsmen began to preach defeatist statements between each other. The remaining marine ended this with a bolter round to the head of a guardsman, its tainted blood squirting over the marine's armour as its head exploded.

Out of the smoke of the artillery shells flung a grenade that landed in a break in the marines armour under his shoulder guard. The grenade exploded, and blew off the marines arm in a spray of blood and gore. The marine dropped dead on the ground. The guardsmen looked at the corpse in shock, and turned to the smoke screen as the rumble of treads could be heard. A spray of heavy bolter rounds and las bolts erupted out of the smoke, killing the traitor guard before they had a chance to react. Several squads of guardsmen appeared out of the fading smoke accompanied by a Leman Russ Demolisher class tank. The Platoon Command squad moved to the front of the advance to survey the damage. The lieutenant nodded, satisfied. He turned around at his weapons specialist, grinning.

"Excellent kill Dorn." He exclaimed.

The trooper nodded with a smirk on his face, a smoking grenade launcher in his hands. From behind the Demolisher a man in a red and black trench coat and peaked cap appeared. He walked up to the lieutenant and surveyed the bodies in front of them.

"Excellent work lieutenant." He said, turning to the lieutenant with a satisfied smile on his face.

The lieutenant saluted the man, holding him in high regard. "Thank you my lord Commissar!"

The Commissar chuckled at the display, "settle down Chase, we've worked together for a year, please just call me by my name."

Lieutenant Chase Williams relaxed himself, breathing a relieved sigh, "Yes Commissar McCullin."

It was now the Commissar's turn to sigh. Commissar Tomas McCullin was a grizzled man in his mid forties, with graying hair neatly combed under his cap. Although he shaved every morning that he could stubble formed on his face. He had a bolt pistol in and unbuttoned holster attached to his belt and in his right hand he held a power sword with the inscription "Sentio Quod Jury" on the blade, an heirloom of his commissariat family.

As the patrol began to move forward a trooper noticed something inside a derelict building. Something moving! He yelled to the lieutenant and commissar to come to him, so they could see it for themselves.

"You better take a look at this sirs" the trooper said to them and gestured the commissar to look. "Something's in there sir, something alive sir."

The Commissar pulled out his bolt pistol and pointed at the doorway. "This is Commissar Thomas McCullin of the Cadian 501st Regiment, and I'm ordering you to show yourself. Failure to do so will force me to open fire!"

In the shadows of the building's interior a figure could be made out. The trooper and lieutenant Williams slightly raised their weapons. Out of the shadows came a boy of around 14 years of age. His clothes were torn and ripped at places and scars were all over his body. He was skinny and looked quite weak and tired, possibly from starvation during the battle for this city. His shaggy brown hair went down to be just above his shoulders and in his limp hand he barely held a battered laspistol.

The Commissar looked at him and quickly requested a medic to treat him. The boy stumbled and began to fall, the commissar grabbing him before he could hit the ground. He felt something strange around this boy, something unique. He continued to think about it as the boy was carried away on a stretcher by Medicae to a Chimera.
