Remember: Contact with an alien force is a recognised felony in both Imperial and Federal law and bears a penalty of death. Should you spot an alien force on your planet, you should do the Following:
1. Do nothing to draw its attention and do not approach it or attempt to make contact.
2. At the earliest possible oppertunity contact your nearest Federal or Imperial building, civil defence office or military/police facility or personnel and raise the alarm
3. Follow any instructions you may be given after raising the alarm in a calm manner. if you recieve no instructions you should gather any family or essential belongings (medication for example) and proceed to seek refuge in your nearest Federal or Imperial building, civil defence shelter or Emperor's Church and remain there until you are told by someone in authority to do otherwise
Grimskul, as he is believed to be called, is the supreme leader of the Ork forces that are currently occupying all of the systems and planets of the Sleipner Sector. He calls himself the Grand Warmaster of the sector and has been in control of the hundred or so planets that make up the Sleipner system since the Federation's Era of Isolation. He is known for being somewhat of a tactician, despite what the Imperial Training Dogmas say about Ork combat, and has claimed the lives of hundreds, if not thousands of Xenos, humans, even other Orks, who have contended his rule and his domain. Standing taller than the mightiest Space Marine and as strong as the best of them he is by no means a stranger to brutal slaughtering and all out attack.
His days are now numbered as the Imperium lauches the biggest campaign against the Green Horde that he has ever come across from any race.
