Roboute Guilliman
From Warhammer 40k
Roboute Guilliman, appeared without explanation on the planet Macragge, a rocky, inhospitable world in what would become known as the Eastern Fringe of the Imperium.
Guilliman's arrival was a time of great omen for the people of Macragge. Konor, one of the two Battle Kings, received a vision of a mighty warrior fighting away the darkness. After leading an expedition to the site portrayed in the vision, Konor found a golden-haired child.
Naming the child Roboute, Konor adopted him, and was amazed at the speed at which the child learned. Roboute was put through the compulsory military training academies, where he became a master of warfare at such speed; two years later he was considered the finest warrior on Macragge. Joining the military, he led a campaign to pacify the previously-unconquered Illyrium, the northern region of the planet. Within two months, he had both pacified and befriended the savage tribesmen.
Returning from his successful campaign, he found his home city in a state of anarchy. Leading his troops to the Senate house, he organised details to bring the city back under control. Entering the building, and defeating a hundred soldiers in the pay of the rival Battle King, Gallan, he found his adoptive father assassinated.
With the assistance of the troops loyal to both him and his adoptive father, Roboute brought the city under control, captured and executed the leaders of the rebellion, and assumed the role of Battle King. As Macragge and the surrounding systems flourished, the attention of the Emperor was attracted.
It was said that Roboute instantly recognized his true father, swearing loyalty to the Imperium and receiving command of the Ultramarines Legion in return.
Oddly, Roboute took a profound dislike to the last Primarch, Alpharius. The Ultramarines had accumulated a fine combat record through strict, structured combat protocol. Alpharius, and his Alpha Legion, believed in flexible planning that included unconventional tactics like sabotage and infiltration. Roboute mocked Alpharius, claiming that he would never be able to match his Legion in terms of glory. During the Heresy, it is said that Alpharius purposely sought out Guilliman in the Eastern Fringe.
The rivalry between the two can perhaps best be demonstrated by a dispute the two had during the Great Crusade. The expeditionary fleet that Alpharius was with came across a world that immediatly rejected the Imperium, becoming openly hostile. Instead of landing his troops and taking the world before it could fully assemble its defenses and prepare, as Guilliman urged him to do, Alpharius chose to wait for months in orbit before he attacked, to let the enemy prepare for it. When questioned about this, Alpharius simply said if he had attacked from the start, it would have been too easy. Guilliman was furious at his brother, stating the war was "a waste of the Emperors bolt shells."
