Caelum is a young aasimar woman with warm brown skin, luminous silver-gold eyes, and long black hair threaded with pale gold strands. A faint celestial glow gathers around her face when she prays, while Lyra's presence often shows through as a sharper silver glimmer in her eyes. She wears practical scale mail beneath white and gold vestments, carries a shield marked with a twin-star symbol, and keeps her holy symbol close to her heart.

Caelum is calm, gentle, patient, and deeply protective. She prefers diplomacy, careful observation, and healing over violence. Lyra is playful, confident, affectionate, sarcastic, and eager for adventure. She is quick to challenge threats and fiercely defensive of Caelum. Both personalities are religious in different ways, Caelum viewing divine power as sacred duty and Lyra seeing it as a beautiful force meant to protect people.

Caelum was born beneath a sky filled with strange golden stars. Her mother claimed that the room filled with warm light at the moment of her birth, and that everyone present heard a voice whisper, “Two paths. One soul.” From childhood, Caelum sensed a divine presence watching over her, answering her prayers when she was afraid. She also spoke with Lyra, a confident, curious, and reckless girl whom her family first dismissed as an imaginary friend. Over time, Caelum realized that Lyra was not an angel or an outside spirit, but another self sharing her body and life. Caelum became the quiet, dutiful one, devoted to scripture and healing. Lyra was the irreverent one, sneaking into kitchens, talking to travelers, and interrupting long hours of study with complaints about boredom. Their divine magic reflected their differences, Caelum's prayers glowing warm gold, while Lyra's power flashed with brilliant silver light.
