Celestials are extra-dimensional beings in the mystical realm of Xonthian, embodying the essence of order in stark contrast to the chaotic demons. These entities, neither strictly good nor evil, align themselves with order, making them powerful allies or formidable adversaries depending on the circumstances. Summoning a Celestial requires a complex ritual involving a sacrifice and a circle of mages or clerics, demonstrating control over the summoned being.
Their anatomy varies widely, displaying a range of body types, skins, and sizes, with some bearing grotesque features while others emanate ethereal beauty. Celestials refuse to engage in direct combat but serve as repositories of profound knowledge. Often acting as messengers for the gods of Xonthian, these celestial beings appeared before individuals like Catt and Tiger during their trials in the mysterious Cave of Passage. The balance they bring to the cosmic order makes Celestials both intriguing and essential in the mystical tapestry of Xonthian.
