Felicia is the great aunt of both Dybbuk and Faustina. She lives on an island in New York, known for its connection to the spirit world. She didn't really like mundanes which is part of the reason she buys the island in the first place. At her house hangs a portrait of a beautiful and striking young girl, aged about ten, which hung above the fireplace.This is later revealed to be Faustina. Both Dybbuk and Faustina sought out their great aunt's island when they were nervous or afraid. She has a deceased butler named Max, which John and Groanin help bury.
