Editing Grimskull (section)

== Graia ==
Grimskull led his Waaagh! to Graia with the intent of looting the [[Forge World]]'s [[Titan (Warhammer 40,000)|Titans]]. Whilst in his cruiser, he encountered [[Captain Titus]] (who used a jump pack to board the vessel from above); whilst the Warboss tried to fill the [[Ultramarines|Ultramarine]]'s body with lead, Titus used the cruiser's cannon to destroy the bridge, making the cruiser crash land. Grimskull survived that wreck.

Grimskull encountered Titus again in Manufactorum Ajakis. While Titus tried to get the mysterious power source for Inquisitor Drogan, Grimskull (who was leading an attack in there), became interested in the device and sought to claim it as his. However, the power source became unstable and loosed a shockwave, which sent Titus plummeting to the sewers. Rather annoyed by this, Grimskull sent his Orks to retrieve it.

As Titus tried to activate the Psychic Scourge (a weapon apparently capable of destroying the Ork invaders), Grimskull arrived by dropship (a minelayer re-purposed for transport). As Grimskull was about to attack, he got blasted by psychic waves. However, to the Ultramarines surprise, this didn't actually kill the Orks, but instead opened Warp rifts that allowed the Forces of [[Chaos]] to enter the forge world. After getting back on his feet, Grimskull was then swarmed by bloodletters, which made him lose his footing and fall over the railings. Whilst Titus and the group were being incapacitated by the [[Chaos Lord]] [[Nemeroth]]'s sorcery, Grimskull climbed back up, apparently defeating the bloodletters without so much as a scratch on him, and engaged Nemeroth in combat after saying the most badass thing an Ork has said in the history of 40k: "''I ain't so easy ta kill''." That said, he got his ass kicked after a short fight which ended with Nemeroth pushing him off the platform, but Grimskull grabbed on and yanked the Chaos Lord down with him.

Grimskull made his final appearance trying to kill Titus; however, the Ork was bested by the Ultramarine and finally executed, his face blown off by a plasma/bolt pistol shot (depending on which of the two Titus has equipped at the time). Without their boss' leadership, the Ork horde quickly fell into disarray, in the face of the arrival of an entire fleet of Imperial reinforcements.

Also worth a mention that when you go encounter him for the last time, he is there relatively unscathed and Nemeroth is nowhere to be found. Now, either the Warboss played dead or ran (''highly'' unlikely), or Nemeroth is actually the one who lost and fled the fight after their fall, but it's more likely that the Chaos Lord simply wasn't interested in scrapping with some random Ork Warboss (what with there being probably millions of Warbosses in the galaxy, few being of any note whatsoever and virtually none of them having anything to do with Chaos or corruption) and went off to accomplish his goals instead.

Post-mortem, the events at Graia would be called the "Grimskull War" according to [[Warhammer 40,000: Boltgun]]. Even with Nemeroth hijacking his [[WAAAGH]]! over Graia with a Chaos invasion, the Imperium seems to at least see him as enough of a threat that the whole incident was named after him.
