Sorceress Vadne is a woman from Xanth, Mundania, then the Isle of Cats in Xanth. Her talent is topology, changing the appearance of things without changing their underlying nature. She was first introduced in Castle Roogna.
Vadne was delivered in 215. She is the wife of Murphy and mother of Grey. She was 21 years old when she was imprisoned in the Brain Coral pool in 236 and began aging again when she escaped during the Time of No Magic in 1043. She would have been 64 years old in 1086 when she returned to Xanth from Mundania, but Com Pewter compressed time, so returned at the age of 40. She is 71 years old.
Vadne is a neo-Sorceress of the past who was not quite a Magician. She was banished to the Brain Coral Pool for changing Millie into a book, killing her. She escaped the Brain Coral Pool during the Time of No Magic. After she and Murphy made a deal with Com Pewter, they went to Mundania and stayed there for 19 years. She was given full Sorceress status by King Dor after swearing fealty to him.
