Keldrin is an imposing figure with deep crimson scales that possess a metallic sheen, reminiscent of cooled magma. His eyes are a piercing yellow, glowing with an internal fire. He wears heavy, blackened chain mail and carries a shield emblazoned with the five heads of Tiamat. His movements are deliberate and rigid, exuding a sense of military precision and suppressed aggression.

Keldrin is cold and disciplined. He believes that the weak should serve the strong and that chaos is a disease that must be purged. He speaks in short, clipped sentences and shows little patience for those who lack a clear sense of purpose. Despite his sinister outlook, he is strictly honorable according to his own dark code.

Keldrin was hatched within a subterranean cult dedicated to the worship of the Five-Headed Queen. Unlike many of his kin who relied on raw savagery, Keldrin excelled in the study of religious law and martial combat. He saw the potential for the Dragon Queen's return as the ultimate opportunity to bring absolute order to a chaotic world, believing only she is fit to rule. After years of training as a temple guard and acolyte, he was knighted as a Paladin of the Chromatic Wing. He was tasked with venturing into the surface world to reclaim lost draconic artifacts and wealth to fund the cult's grand designs. Keldrin views every battle as an offering to Tiamat. He uses his martial prowess not just to kill, but to dominate. His loyalty to his faith is absolute, and he expects the same level of submission from anyone he chooses to fight alongside, seeing himself as the natural leader in any hierarchy.
