Nimue is Lancelet and Elaine's second child and first daughter. In exchange for a love spell, Elaine promises her first daughter to Morgaine to be schooled in Avalon. Morgaine comes to settle this debt when Nimue is only five years old. Shortly after Nimue arrives in Avalon, Raven and Niniane decree that she is to live in seclusion, as told them by the Goddess, so she grows up alone with no one setting eyes on her. As Morgaine's final plan unfolds, Nimue is called forth from seclusion to go to Camelot to seduce Kevin Harper. The plan is to trick Kevin into coming to Avalon one last time, where he will face punishment as a traitor of Avalon. When she goes to Camelot to meet with Kevin, everyone sees her as a beautiful young woman, perhaps more so than when Gwenhwyfar was her age. Nimue becomes so ensnared in the love spell that she works on Kevin that she is just as affected. After Kevin is taken to the grove to be executed, Nimue commits suicide by drowning herself in the lake.
