"Since establishing his home stomping grounds amongst the northern peaks of the Worlds Edge Mountains, Grimgor has found time to butcher his way through many other territiories. Stunties, encased in their nigh-impenetrable armour were hacked apart with ease. Vampire Lords from Sylvania were broken and their fangs strung onto long ropes to bedeck Grimgor's banners. When he marched into Kislev Grimgor found, to his dismay, that even a dozen of their best champions could barely make him break a sweat... To the north Grimgor's quest took him, for he heard that in those lands the men and beasts were fierce. The first to suffer were the Skaven, as he stumble upon the lair of Hell Pit. For a while this proved satisfying, as Grimgor slaughtered grotesque, multi-headed beasts and warpstone-addled monsters. When the master mutators ran out of creatures, Grimgor grew disinterested... It wasn't long after that Gringor and his followers began meeting the wandering northern tribesmen, the followers of the Dark Gods. These proved disappointing in battle, at least at first, until larger and more heavily armoured forces began seeking out the 'green demon' that was stalking the wastes, but even there harder armies were soon destroyed. In his wake, Grimgor left piled mounds of hacked apart Chaos armour, like empty bones or shells tossed away after a feast. A feeling as unwelcome as non-stop Goblin jabber-talk had been growing  in Grimgor's black heart. What if nothing that walked, crawled or flew could put up a good enough fight? And then, finally, at the foor of the High Pass, Grimgor found his equal in battle. He was fought to a standstill by a champion of Chaos named Crom the Conqueror. If the combat had been allowed to continue, Grimgor felt sure he would have prevailed, but his greenskin army, soundly beaten, was fleeing southwards. Even Grimgor knew he could not stand alone against an entire Chaos army, although it galled him to back down. This setback, a drawn combat, only further stoked Grimgor's lust for battle."
