In Celtic myths, the figure who often acts as a guide to the otherworld is Brigid or a Druid. These characters facilitate the transition between the living world and the realm of the dead, representing wisdom, healing, and enlightenment. They embody the cultural understanding of death as a continuation of the life cycle rather than an end; guiding lost souls helps underscore themes of transformation and rebirth. This role reflects the Celtic belief in the cyclical nature of existence, where the otherworld is seen as a place of rest and renewal.
