The 27th of Vult, Khybersef, is the first day of winter. The shortening of the days is thought to represent the balance in power shifting between the light and the dark, where dark forces are emboldened. It is likely no coincidence that the Flamic holiday of Khybersef coincides with Long Shadows, where worship of the Shadow is in focus and its followers are encouraged to chase their ambitions, stepping over whoever gets in their way.
Communities will treat Khybersef differently, but a common tradition is to light up the night with silver candles to chase the darkness away. In some communities, especially since the end of the war, the faithful have begun creating dazzling magical light displays in public parks and shared spaces.
It is also common for followers of the Flame to fast on Khybersef, and then spend the following day feasting with the rest of the community, taking a large communal meal.
