The Festival of Arúyn, or Faylon Arúyn, is celebrated as the nights begin to get longer. It begins at sunset on Chelydaans 15th and continues into the evening of Chelydaans 16. The ancient Sonaide Bri considered it to be the start of their new year, a day when the walls between the living and the afterlife were thinnest. Though modern Sonaide Bri have adopted the Common Calendar, this remains an important holiday, for it is believed that the the Wild Hunt is fiercest on this day. Youngsters celebrate with spooky costumes and parades meant to simulate the Wild Hunt, while the most devout observe with prayers to protect the spirits of the recent dead, that they may be safe from the Hunt.
