CELESTIA : The Guardian Caelum

Before Thrones, There Was One Light.
In the dawn of Celestia, only one kingdom stood - a realm of harmony ruled by Orion Caelur, the Lightborn sovereign touched by both Astralis fire and Aetherian grace. But as celestial beings grew divided in virtue and vision, Orion called forth the Twelve Thrones, birthing the Zodiac Kingdoms to preserve cosmic balance. Yet from the silence came a thirteenth: Ophiuchus, the anomaly whose very presence unsettled the stars. To hold the scales between order and discord, Orion became the first Guardian - eternal, impartial, and alone - bound to balance the cosmos, never to belong. Thus began the Age of the Twelve... and the long echo of his sacrifice. An echo now carried by Caelum - the Guardian destined to bear the weight of the stars.
