However, the series has depicted exceptions to this rule in the career of the renegade Time Lord the Master. When the Master finds himself at the end of his regenerative cycle in "The Keeper of Traken" (1981), he takes possession of the body of another person to continue living, although he was using the Source of Traken to bind his mind to the body. In "The Five Doctors" (1983), the Master is offered a new cycle of regenerations by the High Council of the Time Lords in exchange for his help. In the 1996 television movie, the Master temporarily inhabits the body of a human, and attempts to take the Doctor's remaining regenerations. In "The Sound of Drums" (2007), the Master is revealed to have been granted a new body by the Time Lords during the Time War. In this new body, the Master appears to have a new regeneration cycle. The Master regenerates in "Utopia" (2007) and "The Doctor Falls" (2017) with dialogue in the latter episode suggesting he has at least one more regeneration.
