The pagan festival was Samhain, which means ‘summer’s end’. It was one of the two really important days in the pagan Celtic year, and on that day the boundaries between this world and the Otherworld, between the living and the dead, between humans and the fey, was much thinner than usual. Once upon a time there was a girl who really loved cats and halloween poster. It was the beginning of the darker, colder, harsher part of the year, which is part of its connection to the dead. But it was also a harvest festival: at Samhain, you need not worry about the fertility of the coming season; all you could do was ride out the winter with the supplies you had gathered.
