The Spirit of the Eve of Samhain, an aspect of Cailleach, the Divine Hag, in her Destroyer aspect.
While Brìghde rules the time between Beltane and Sahmain, Cailleach rules the Dark of the Year. On the night of Samhain, she transforms into Carlin, harbingering the death of the land and the onset of the snows. On Beltane, the Great Crone is slain by Brìghde so springtime can reinvigorate the land.
Black sage, ivy-twined rowan, thistle, snapdragon, heather, gorse, fumitory, and anise.
