From the Back of the Book:
Welcome to Invidia, where Vistani curses come to their terrible fruition. As a young girl, Gabrielle Aderre was warned by her mother never to have children: "A man, a babe, a home -- these things can never be for you, for tragedy will be the only result." Now the witch Gabrielle has disobeyed her mother and borne a child, an abomination that could spell doom for Vistani everywhere. Gabrielle has learned too later the truth of her mother's prophesy.
The Evil Eye is a series of six scenarios involving the Vistani and their most hated nemesis, the legendary Dukkar. The adventures uncover the hidden secrets of Karina, the largest town in Invidia and home to the most terrifying festival in Ravenloft. The heroes will arrive to see a town in the throes of Carnival -- a time when ghosts and madmen, werewolves and gypsies all mingle under the waxing moon.
Inside this package is a 64-page book containing all the information needed to run the Evil Eye, plus a full-color mapsheet showing the laps of Invidia. Van Richten's Guide to the Vistani and Van Richten's Guide to Fiends are helpful sources of information to expand and enrich these adventures, but are not necessary for play.
