Winternight is a holiday marking the last day of winter. It is celebrated the night before Bel Tine and participants typically spend the night visiting one another, exchanging gifts, and eating and drinking together.
The Winternight attack
In 998 NE, Winternight held special and tragic significance for the village of Emond's Field in the Two Rivers, when Trollocs and at least one Myrddraal attacked, searching for the youth that would become the Dragon Reborn. Their attack failed due both to the customs of Winternight in the Two River's area, and to the fortuitous presence of an Aes Sedai, Moiraine Damodred, and her Warder, Lan Mandragoran. The pair had come to the Two Rivers region in search of the same young man, and following the attack took several young residents of the village away for their own protection, although many villagers, fearing the Aes Sedai of their stories and legends, were suspicious of their true motives.
