From a young age, Kah displayed key military and leadership traits that brought him praise by those he interacted with. At the age of ten, he began training to become a soldier, becoming widely known throughout the Niraxian military community. His hard work eventually saw his induction into the Niraxian Zealots, with whom he would forge a close bond.
Following the Niraxian defeat at the Battle of Wesdenrath, Kah mobilised the Niraxian Armada and planned the counter-attack. Kah would continue to bring glory to his nation until his death in the Third Battle of Therhold. He was succeeded as Champion of Niraxia by his younger brother Nikriontra.
Kah is regarded today as one of the Empire's greatest heroes, and continues to be mourned. He is presently interred in the Imperial Mausoleum on Niraxus 7.
Katriontra was born 17 October 1795 as the first child to King Akriontra and Queen Daryci. He was named after Katriontris the Legendary, a Niraxian hero whom Akriontra revered. Growing up, Kah exerted signs of leadership and strategy and became popular among his classmates. His father, seeing the potential in his first-born son and heir, authorised Kah's training in martial arts at a young age. By the time Kah reached his teenage years he was already a skilled close-quarter fighter. He was trained by the Niraxian Armed Forces' best military teachers and developed a reputation as a future warrior and potential Niraxian Knight.
When Kah reached adulthood, he was inducted into the Niraxian Zealots, the elite unit of the Niraxian military. There, he formed a close bond with twelve Zealots, who bound themselves to serve in him in battle under a blood contract.
