"The Wines of Barovia" recounts the rich history of the Wizard of Wines and its legacy of wine production. Teleportation Circle: Centuries before Strahd's reign, two ancient teleportation circles were crafted, each with its unique purpose. One of them lies hidden in a shallow cave (W15) beneath the Wizard of Wines, while the other is located within the Wine Cellar (K63) of Castle Ravenloft. It's possible that the circles were used to transport wine from the vineyards to the castle, but their true purpose has been lost to time and memory, and they have remained untouched for centuries. To activate the teleportation circle, one must recite the wine blessing incantation (found in the book) - a powerful invocation that has been used to bless the wines of the Wizard of Wines for generations. Though the teleportation circles may have long been forgotten, their magic remains potent, ready to transport any who dare to step upon them. The book is common and sold in the bookstore in Vallaki.
