Amiir was born into a military family and was trained in the art of war from a young age. He quickly distinguished himself on the battlefield as a disciplined and focused soldier, earning the respect of his comrades and superiors. He rose through the ranks of the Khein Dynasty's armies and became one of its most trusted commanders. At the end of the Second Age the forces of the Silver Dominion invaded the territories of the Dynasty. Amiir rallied the forces at the border and established a strong defense while the Princes was marching to the border. He and his forces managed to hold off the enemy for days before Ahriman arrived with his army and turned the tide of the invasion. When Ahriman returned after pushing the enemy back into the Dominion territories, he was met with Horus who stood beside a kneeling Amiir and saw another Prince rise. He was given the responsibility to continue the defense of the southern region of the Dynasty, something Ahriman hated at the time.

As the defender of the southern border, Amiir oversees the construction and maintenance of fortifications and defenses along the border with the Silver Dominion. He trains his soldiers in the art of siege warfare, ensuring that they are well-prepared to repel any invading force. He also works closely with Alikhan, who provides the necessary funding and resources for the defense of the southern border. In times of war, Amiir is a skilled tactician, able to anticipate and counter his enemies' moves. He emphasizes discipline and defensive strategies, preferring to wear down his opponents rather than engage them in costly battles. He is known for his patience and his ability to withstand long sieges, as well as his ability to inspire his troops to hold the line against overwhelming odds.

Despite his focus on defense, Amiir is not afraid to take the fight to the enemy when necessary. He is a skilled commander of siege weapons and can lead devastating attacks against enemy fortifications. His ability to adapt to changing circumstances and his unwavering commitment to his cause make him a valuable asset to the Khein Dynasty's army and a respected Prince of Horus.
