In addition to the information known to all Barovians (see "Barovian Lore" in chapter 2), the villagers of Krezk (called Krezkites) know the following bits of local lore:
Residents never leave the village for fear of being attacked by wolves, dire wolves, and werewolves.
About once a month, a wagonload of wine arrives from the Wizard of Wines (chapter 12), the winery and vineyard to the south. The business is owned and operated by the Martikovs.
Burgomaster Krezkov recently lost his fourteen-year-old son, Ilya, to illness. Ilya was the last of the four Krezkov children.
A pool at the north end of the village provides fresh water throughout the year. Next to the pool, the village's ancestors built a shrine to the Morninglord in a gazebo. It's known as the Shrine of the White Sun.
The abbey was once a hospital and a convent, but it fell on hard times after the land was swallowed up by the mists. Some of the clergy fell prey to Strahd, while others went mad and either starved themselves to death or turned to cannibalism.
The head of the abbey, called simply The Abbot, arrived over a century ago and hasn't aged a day since. He occasionally visits the Shrine of the White Sun but doesn't talk much, and he demands tribute in the form of wine. No one knows his true name or where he came from, and many believe he's Strahd's servant or the vampire himself in disguise.
No one from the village visits the abbey anymore. The abbey's bell rings at odd times, day and night, and the place is filled with baleful screams and horrible, inhuman laughter that can be heard throughout the village.
