Arabelle is a young prodigy of divination magic. She was kidnapped by a man from Vallaki and almost drowned in a lake but was rescued by Team TRASH (pandas), with help from her father and uncle. To show her gratitude, she agreed to read the fortunes of the party using Tarokka cards. Thus far, her reading has been accurate.
Arabelle is also the great-great-granddaughter of Ludmilla Vilisevic, a vampire who resides in Castle Ravenloft with Strahd Von Zarovich.
