The Umbral Sundial takes the form of a crystalline disc etched with intricate celestial markings and symbols. Its translucent surface refracts light in mesmerizing patterns, casting kaleidoscopic shadows that seem to shift and dance in response to celestial alignments. Despite its delicate appearance, the Sundial is imbued with ancient magic, allowing it to track the movements of stars and celestial bodies with uncanny precision, even in the deepest darkness.

Though lacking overt agency, the Umbral Sundial's presence triggers strange phenomena and environmental anomalies that drive the investigation forward, from sudden temperature drops and ice formations to celestial disturbances that defy natural laws.
