Starting in 326 AC, Celtheon quickly rose up the ranks, winning the admiration of Aegor, and later, his son Taeronys Dragomyr, whom he was close with and personally trained. He yearned for earning his place in the ranks, and so frequently acted out dramatically or in a risky way to make his actions clear and visible. While most times this was met with either laughter or scolding, Celtheon was the one to ultimately track down and slay Dalan I Karthmere during the Six-Day-Siege -- this alone earned him a promotion to the rank of Captain at the start of the Tentative Years, which he would hold until he became a lesser general in the early 340s AC, and eventually, the commander of all Andoras's armies just before the beginning of the Civil War.
