He was rather unnoticed by his subordinates when he began, and it took over 30 years for him to start moving up the ranks, until he became an officer in 234 AC, under the Grandmaster Juslian di Vyse, and remained so after Juslian's uneventful death in 238 AC, at which point Jorry 'Lavos' became the Grandmaster of the Broken Cloaks. Celomar was close with Jorry, mainly because Jorry had been assigned to Celomar's training regiment when he joined in 227 AC. Celomar offered something that most other trainers could not; he was a gifted tactician and taught his pupils these same tactics and how to apply them.
Keeping Celomar close after his placement, Jorry introduced him to Garryt and Kallum after becoming Grandmaster, and assigned Celomar as his head advisor on matters of conflict. Ever since then, Celomar had dwelled where the front lines were, moving himself and his few personal belongings every time one of his successful assault plans came to fruition. To most men, he was kind and wise; harsh, perhaps, but kind, a trait rarely seen among men in his line of work. To the Odd Three, however, he was something of a father figure, guiding them in matters both physical and psychological.
He remained faithful to the Broken Cloaks until his tragic death in the Efugian Massacre on January 12th, 242 AC, at which point the war effort was on its last legs, no matter how one looked at it. After his death, Jorry and Garryt became depressed, and lost the will to fight. The Lavosi Gang Wars ended on the 1st of February, just four weeks later. When they later unsuccessfully attempted to assassinate Victor Damius two years later, Celomar's death was cited as a chief inspiring factor.
