The Outbreak.

On 6/07/ (according to Terra's time) it was incredibly hot at testing facility #781, and because of this most of the "elite" guards had gone swimming in the nearby lake during their time off duty. As brother-captain Destel Jalan looked out on them from the window by his desk he scowled. He knew that it was a bad idea for them to be so far from the premises of the lab but, after all they were only human and needed that. Then he grinned remembering once as a youth on Titan when he had gone swimming with a few of his brethren, but those days were long gone. "Sir, it's time to call in the night shift." Said a cool airy voice from behind him. Jalan jumped and spun around on the spot to find himself face to face with Le-Sen a member of "Ordo Hereticus" who was one of the twisted scientists working at the lab. Jalan looked down on the man and said: "I am aware of the time Le-Sen. May I ask what you are doing here in my office?" Le-Sen coward under Jalans stern look and gazed intently at his boots. "Sorry sir I should have knocked." He said slowly and cautiously. "Right you are. Now leave me and I shall cal out the night shift." Jalan said authoritatively. Le-Sen turned around and left the office.
Lt. Simon Lusel had just turned a corner and came face to face with a metal door that lead to the main testing room. He knocked once, with no reply. Then drawing his hell-pistol from its holster at his side he slowly pushed open the door. Inside were the scattered bodies of almost all of the examiners and scientists. Lusel raised his hell-pistol looking at the destruction. Tables were over turned lamps were smashed on the floor surgical instruments lay scattered around the room. Then out of no were a form sprung forward to face him. It had the resemblance of a man with two dangling spiked balls coming out from either arm, it was an arco flagellant. Lusel screamed and shot it 4 times in the face before it could move. Then he shut the door locked it and sounded the alarm. The alarm woke up everyone in the building and there was immediate chaos the arco flagellant had opened several cells and testing rooms and killed three storm troopers before a well placed psycannon shot blasted it in two. But by that time hundreds of prisoners had been set free. Now the fight had begun. The main goal of the defending storm troopers and grey knights was to block off the main halls. Their adversaries were poorly armed and armored and the defenders managed to completely mop the place up in less than two hours. By the end every single prisoner or detainee was dead and all the passageways secure. Over the whole course of the battle two grey knights had fallen (to a nasty daemon that had been summoned by a rouge phyker into one of the narrow hall ways and had struck them from behind) also 18 storm troopers lay dead. Jalan wiped his forehead and vowed never to seek out those responsible, and bring them to justice.
