Mogrok - Warboss Grukk: Mogrok convinced Grukk that rather than fighting a few Orks on some backwater planet, he could be conquering whole star systems. It took a while, but the Mek eventually awoke a spark of ambition in Grukk. The Ork charged back to the Goffs' fort and smashed his way into Krugg's ramshackle hut, knocking the Warboss from his feet with a roar of challenge.The Tyrant fought back with savage brutality, battering Grukk bloody. The two Orks tore the fort apart in their struggle, and eventually Krugg caught Grukk with a thunderous backhand blow of his saw-fisted Power Klaw, hurling his brutish challenger through a mudbrick wall into the dusty courtyard beyond.As he loomed over Grukk's crumpled form, Krugg prepared to land the finishing blow. Grukk's will to kill drove him to his feet at the last moment, grabbing the Tyrant's roaring saw-klaw and forcing it inexorably backward.Green sinews shook and muscles bulged as the two Orks strained against each other, yet Grukk was stronger. Krugg's eyes widened in horror just before his arm broke with a rotten crack, and the Power Klaw's roaring saw-blade chewed hungrily into his face. Blood flew in sheets, and with that first conquest, the Warboss Grukk Face-rippa was born.Skagfing had only recently heard about his rival's death when Grukk and his ladz smashed their way into the Bad Moons camp, the Goff Warlord sacrificing loads of Boyz as Grukk charged in and pinned Skagfing down, stood on his chest, and messily ripped his face from his skull.In a single bloody blow, the Split-Grins were absorbed into the Skullcrackers and Grukk took control of the united tribe. In Skagfing's place a bunch of Nobz tried to bully their way to the top, but none of them could match the raw aggression and prodigious size of Grukk. Within a solar week, Warboss Grukk had united the Orks of Eyrok, crushing any rivals to his position.As he stood over the fallen Warlord of the Split-Grin tribe, Mogrok was there again, talking in Grukk's ear, telling him about some nearby worlds where there was fighting to be had. Now with free access to all the scrap he could use, the Big Mek hammered a voidship together and found the Freebooterz that had marooned him on Eyrok.He brought Grukk with him to teach them a lesson, and those that survived the ensuing battle soon joined up with the Warboss. Fragmented and leaderless, the Split-Grin tribe became inferior to the Skullcrackers. Grukk used the tribe for its massive guns and kustom weapons, draining their stockpiles to build up his warband. The Split-Grin tribe also gave Grukk access to the Sanctus Sub-sector's Freebooterz, giving the Ork Warboss a way off Eyrok and out into the void.Not long after Grukk started raiding the edges of the Sanctus Sub-sector in the Ultima Segmentum, Gashrakk da Flash (an irritating Flash Git who once served as Kaptin Badrukk's first mate) figured out that as long as he avoided the big Warboss' temper (no small feat) he could talk the single-minded Goff into giving his Split-Grin tribe the choicest enemies to fight and the best bits of a world to attack.On the moons of Palos, while Grukk's mobs cracked their way into the domed cities, Gashrakk plundered the world's diamond mines, allowing the tribe's Meks to use the gems as lenses and ammunition in Kustom Blastaz or Big Gunz, and the Painboyz to give the richest Nobz new sets of "shiny teef".On the prison planet of Night's End, the Split-Grin tribe made piles of teef running the pit fights, Gashrakk personally blasting one particularly tough prisoner to bits when it looked like he might upset the odds. More than once Gashrakk put Grukk's loot in his own ships "for safe-keeping" and waited for the Warboss' attention to be drawn to another fight instead.Mogrok would have challenged Gashrakk for trying to use the Red WAAAGH! for his own ends, if the Big Mek wasn't doing precisely the same thing himself. In fact, the effectiveness of the Split-Grin tribe's kustom weaponry allowed Gashrakk to get Mogrok and his Mek followers to make several Gorkanauts and Morkanauts for the Split-Grins.The Freebooter even managed to lay claim to one of Mogrok's Stompas, and the Split-Grins were soon accompanied in battle by an ever-expanding horde of smoke-belching combnat walkers. Soon, what began as isolated reports and garbled astropathic missives quickly built into an avalanche of desperate cries for aid.Grukk mercilessly ravaged the toxic jungle moons of Palos, breaking the great crystal dome of its blessed city and flooding it with poisons while his warriors looted and killed. On the penal outpost of Night's End, the Orks turned the prison into a giant fighting pit, throwing in Squigs, Grots and Boyz while placing bets on how long the Human prisoners would last against them.When the Imperial Sector Lord Vargan sent his periphery fleet against Grukk, the Orks attacked them in the midst of an asteroid field. Ork and Imperial vessels were hammered with rocks as they blasted each other to scrap, the Orks ramming, battering and boarding dozens of Imperial vessels.With every raid and battle more Orks flocked to Grukk's banner, and his legend took root in the minds of Greenskins across the breadth of the Sanctus Sub-sector. In the space of a few short years, a sector of space considered desolate was teeming with Orks, all bawling the name Grukk into the dark.
