In the four years after his exile, Temujin had grown into a great warrior and skilled horsemen, fueled by his hate and thirst for revenge. While Todoyan Khan of the Taichi'uts ruled over most of Mongolia, in the lands of the Tartars Temujin thrived. Still barely accepted amongst the other clans, the outcast Temujin was warmly accepted by the broken tartar clans after he proved himself. After leading several sucessful raids against the Jurchen, by 1178 A.D. Temujin had won for himself a place of respect and power within the tartars, this of course was not enough for the man who would one day become Genghis Khan.
Haunted by the memory of his father and the treachery that had prevented him from achieving total unification of mongolia, Temujin looked north of the tartar lands to the remaining territory of the Lamutes. Gathering to him many greedy and bloodthirsty warriors, Temujin decided that to win his vengence, he must first spread his name and influence. In April, Temujin and his loyal horsemen rode into the Lamute lands. The men who rose against him were cut down, the women and children smashed under foot. For over a year Temujin and his bloodthirsty warriors fought, pillaged and conquered the lamute lands and as he did, his name and reputation spread, gathering to him more and more disenfranchised fighters to him. The Lamutes had suffered enough and could fight no more, bowing before the superior organization of Temujin. They soon acknowledged Temujin as their leader, causing the new Tayichi'ut Khan, Aguchu to grow worried.
Over the following years, Aguchu Khan could only watch on with horror as Temujin's name spread and with it his influence. Aguchu put out rewards for Temujin's head, but most did not accept. Those that did either joined the growing army of the exile, or found their heads severed from their bodies and returned to their master to Aguchu's disgust. With each passing year, Aguchu Khan and the Jamuka coalition (the elders who did not accept Temujin as their leader when his father died) grew more afraid, relations becoming tense, causing bickering and infighting to errupt. This only aided Temujin and he soon found himself in the position to write history with his sword.
By the beginning of 1182 A.D., while not yet even twenty years of age, Temujin had grown into a fearsome warrior and honored leader. Declaring that the cowards of the Jamuka coalition had caused the death of his father and usurped his power and the destiny of the mongol people, Temujin made it clear that he had returned to right the wrongs done unto him. Taking the title, Great Khan, or Genghis Khan, Temujin broke the control of the Tayichi'ut's over the rest of the clans. With thousands of veterans from his years of exile, Temujin Genghis Khan invaded the north lands, knowing his time of revenge was finally at hand.

In truth, the Tayichi'ut's did not put up much of a fight. Temujin and Genghis Khan became the name on every mongol's lips. For eight months Temujin and his forces overwhelmed the Tayichi'uts, slaughtering their forces at every battle. The great khan did not stop there though, Temujin hunted down every last member of the Jamuka coalition, then before slaughtering them like sheep, killed their children before their eyes and took their women or if he wasn't up to it, had one of his soldiers do it. Aguchu was spared that particular death, killed by an arrow to the throat in one of the early battles. Yet even with his enemies dead, Temujin felt unsatisfied. His vengence left him empty inside and at first the only thing he had to fill that space was hate. Ordering the death of all of the Tayichi'ut men, the Khan's army butchered the once proud Tayichi'ut, former allies, for another month. The women were spared, but the Tayichi'ut were no more.
Having built for himself a throne from the bones of his enemies, Temujin began the process of forging an empire fitting for such, one carved out at the end of a sword and fed from the flesh and blood of all who opposed him. The reign of Genghis Khan had only just begun.
