Samhain

In the Celtic tradition, Samhain is a festival or time of transition marking the end of the harvest season and the beginning of winter. It is described as the 'darker half' of the year, suggesting a liminal period between the light and dark halves of the year.

Samhain is described as a time of transition and a festival marking the end of one season and the beginning of another, rather than an entity with specific powers or behaviors. However, it is implied that during this time, boundaries between worlds may be blurred, allowing for interactions with spirits or other entities.
