This small, flickering ball of light resembles a candle flame.

Canwyll corphs (CAN-noo-WILL-cor-F) are the spirits of the dead. They vary in color and size, indicating the gender and age of the person destined to die. The candle’s light hovers near the ground, floating silently through the air. It has an ethereal quality, seemingly detached from the physical realm. Those who can see into the ethereal plane say canwyll corphs appear as floating skulls, with the flickering light emanating from just behind their eye sockets.

Each size and color identifies who it was in death. Small white canwyll corphs are the souls of adult female humanoids, while small red ones are adult male humanoids, and small blue ones are infants or toddlers. Tiny blue canwyll corphs are the spirits of young humanoid children of any gender. Occasionally a small white canwyll corph will be seen with a tiny one, indicating the spirit of an adult female humanoid and her unborn child.

Canwyll corphs are mischievous and unpredictable. They are known to appear near the homes of those about to die, tracing the path the funeral procession will take to the burial site. The lights may also be observed hovering over graveyards, swamps, or the location where a grave will be dug. When a person sees a canwyll corph, it is believed to be an indication of their impending death or the death of a loved one.

Despite their ominous nature, canwyll corphs are not aggressive creatures. They do not actively hunt or engage in combat. Instead, they serve as spectral omens, guiding the living to the realm of death. Their presence is often associated with supernatural phenomena, creating an atmosphere of foreboding.
