The Festival of Brigga ap Ítharnae, called Fayluh Brigga, is a midwinter festival sometimes called the Festival of Lights or the Festival of Candles. It begins at sundown on Chryadaans 15, the 46th day of the Common Calendar year, and continues into the evening of Chryadaans 16. The Sonaide Bri celebrate it by lighting candles or lanterns in prominent windows, or sometimes on the front porch or elsewhere in front of the home. It is a feast day marked by hearty fare, when possible.
