As the haunting season is creeping up, we’ve summoned … Baba Yaga. An icon of Slavic folklore, this enigmatic woman can be your best friend or your worst nightmare, depending on her mood. While you’ll usually find her in her hut deep in the forest, Baba Yaga emerges each October to join a cast of other macabre characters at Legends & Lanterns, a free Halloween celebration on Main Street in St. Charles.
