Ghazghkull Mag Uruk Thraka - Octarian War: Octarius had been Ork territory for many thousands of standard years. It was not as backwater a subsector as where Urk had been, and every so often a leader would rise up, call a WAAAGH!, and lead an invasion off to wreck some part of the galaxy. Indeed, the old Warlord Gorsnik Magash had rushed off to join Ghazghkull in the Golgotha Sector and was currently heading a vast force of Orks on Armageddon, holding his own in the Dead Lands. Since Gorsnik's departure, a new leader had quickly risen to fill the power vacuum and claim the title Overfiend of Octarius -- a Deathskull Warlord named Zog Steeltoof.Despite his copious use of blue warpaint, the rule of Zog Steeltoof had thus far not been a lucky one. Tyranids had returned, sweeping into the biomass-rich Ork territory, consuming entire planets as they advanced. The fight, known as the Octarian War, raged across the whole sector, its epicentre squarely targeted upon Octaria, the central world of the greenskin territory. The entire mega-continent of Octaria was a battlefield into which both sides poured their might. The Overfiend's Orks, grown big and strong on their diet of constant war, had met their match. The ever-evolving spawn of Hive Fleet Leviathan were gaining the upper hand, showering the planet with reinforcements, sending yet further broods of killing beasts into the non-stop melee. Across Octaria the Orks were forced to take refuge in scrap-iron fortifications. It seemed only a matter of time before the Tyranids collapsed each of the jury-rigged fortresses. Then WAAAGH! Ghazghkull descended from the spore-ridden skies.At first, the Overfiend's Orks thought the Roks blazing through the atmosphere were some kind of new foe. All across Octaria they landed, smashing gaping holes through the Gargoyle-filled skies and ploughing into the scuttling hordes on the ground. It was not slime-covered, chitin-plated Tyranid creatures that emerged from the asteroids, however, but more Orks. They surged outwards, taking the fight to the Tyranids while the Roks themselves opened up with heavy calibre ordnance. The greenskins behind their shabby defences let loose volleys of cheers and a hail of supporting fire of their own. Then came the heavy, ground-shaking footfalls of incoming creatures of immense size. The Hive Mind had noted the arrival of these invaders.The Tyranid response was frighteningly quick. Larger swarm creatures-- hulking scythe-limbed horrors and Gargant-sized beasts -- lumbered to oppose this new greenskin threat from the skies. The raucous chants of Octaria's Orks died in their throats, for they knew that these towering behemoths had been held in reserve, saved for the final death strike. When the Orks' defences had been breached, these monsters would have arrived. Now the newcomers would be shredded, for there could be no hope for infantry out in the open.To their surprise, the air flashed as Tellyportas began to bring more reinforcements. All across Octaria, the cratered Rok landing sites now blazed with unnatural lights. After each flash, more and more mobs appeared, and these were not just infantry. Arriving with guns chugging, Gorkanauts and Stompas concentrated their firepower on the larger foes, while at their feet Burna Boyz mobs spread out. With each blast from their weapons they sent blossoms of red fire leaping out to flash-fry the lesser creatures in droves. Amidst the mobs pouring forth, countless crude banners and totems could be seen, carried high by the newly arriving troops or mounted atop clanking Battlewagons. The Orks of Octaria saw the symbols and knew who had arrived...At Gargates, the Overfiend's shanty capital, Ghazghkull Thraka himself appeared via Tellyporta. He led the charge at the head of his Bullyboyz as they crashed through the serpentine Raveners that were beginning to undermine the first lines of defence. To the Greenskins that watched, this massive Warlord in Mega Armour fought like Gork himself. He wove in and out of sight in the swirling carnage, but he was easy to pick out. An aura of green brutality seemed to surround him and he clobbered each of his foes so hard that limbs, heads and claws flew in bloody arcs all around him. He moved like some elemental destructive force, a one-Ork wave of destruction. His Kustom Shoota spat death and with every swipe, Ghazghkull's Power Klaw sliced multiple foes in half. Every motion, from his elbow backswing to the stomp of his iron-shod feet, cracked the shell-like armour of the Tyranids and sent more to fall, thrashing their death throes on the blood-strewn ground.And then the unbelievable happened.The body-strewn landscape at Ghazghkull's feet seemed to buckle and bulge upwards. Then Ghazghkull was gone. A Mawloc had come. It burst from below and, as its bulk breached the surface, the creature coiled about itself like some hideous constricting serpent. This was the largest such creature any of the assembled Orks had seen -- the deadliest spawn of its kind that ever slithered underground or was seen by the light of any sun. The triumphal screech that burst from the beast's gaping maw twisted metal and made Orks miles away fall and cover their ears. Even before its screech of victory was over, however, something had gone wrong. The Mawloc heaved -- flopping its mass so that it seemed the world itself trembled. Then the beast quivered, writhing in convulsions, twisting its mighty coils in arcing loops. An unnatural bulge formed in its midsection and out thrust a Power Klaw, amidst geysers of gore and slime-covered entrails. Shoota blasts widened the hole and out stepped Ghazghkull, striding out of the very belly of the beast. The mightiest of Ork Warlords roared his victory to the skies, a rallying cry to greenskins and a challenge to all else that lived.After that, nothing could stop the Orks. Chanting their Warlord's name, the greenskins of WAAAGH! Ghazghkull went on a kill-rampage, hacking, shooting and slaying in a berserk frenzy. From behind scrap-iron walls, the Orks of Octaria burst forth to join in. Even Zog Steeltoof, the Overfiend of Octarius, was chanting the name Ghazghkull as he gunned down the living wall of Tyranids that attempted to stay the greenskin onslaught. A great butchery began, and it did not stop until Octaria was free of the creatures of the Leviathan.
