Chapter 1: Approach of the Chaos Space Marines

Threw slip space came a ship. It was not Covenant or Human. On the side was the insignia of the Daemon Lords. War had attracted them here. It was in there blood to fight. They had grown tired of their past war and searched for new opponents. They had found it. A planet made mostly of water and had huge lands for the taking. It was a planet called Earth. In cryogenic-sleep was the greater Daemon of Khorne. He had Khorne Berserkers sleeping along side him. Terminators and Plaguebearers as well as Plaque Marines commanded the ship. In the distance was a sleek ship. It resembled a fish with stiff fins. It was a covenant cruiser. There plasma turrets followed the ship. There plasma glowed a burning bright white. In a flash the cruiser had begun its assault on the cruiser. The Covenant laughed at the head of the ship. There laughter was soon to awe. The cruiser that they had attacked was still whole. The plasma turrets began charging again. From the ship launched a barrage of missiles. They struck the side of the ship where the plasma turrets were located. The shield didn't go up in time and huge holes were left in there place.
The Plaguebearers laughed demonically. One of the Plague Marines escorted them out as they were disrupting the Chaos Marine that was commanding the weapons. The covenant ship turned on its other side and charged its last remaining plasma turrets. Once again, several missiles struck the side of the ship before the shield could go up. Bird like creatures and short stubby creatures, along with several tall multi-colored aliens floated out of the ship and bumped against the inside of its shields. Several heavy looking aliens stood at the opening left from the missiles and crouched over. They wore heavy armor and their guns began glowing a bright green. Several bolts of energy struck the side of the ship with no damage. This confused the Covenant. Before they had been able to take down human ships so easily, now they couldn't do a thing about it. Several beetle like fighters flew our of the Covenant cruiser. The guns on the new ship were armed. The covenant fighters swooped around on the ship. The guns roared and bullets were dispensed into space.
The guns were so powerful that the bullet was not slowed by the zero gravity and pierced the fighters. Several fighters spun out of control and went into deep space. The Covenant cruiser shifted its course.
"Take out that enemy ship before it escapes of the greater daemon will have your head," barked a Chaos Space Marine. The Plaque Marine next to him was use to this. He nodded and armed every weapon they had. An EMP missile was launched at the enemy ship. It blew up and knocked out the Covenant ships shield. All the Covenant bodies being held in were released into space. Missiles were launched and guns were shot. The Covenant cruiser was torn to shreds as the Greater Daemon of Khorne awoke with his Khorne Berserkers. A Chaos Terminator bowed.
"Lord, we have reached a planet under war. We are approaching it as fast as we can." The Greater Daemon smiled evilly.
"Another planet for us to conquer in the name of chaos. Very good. Prepare our troops."
