Exile

An exile was an individual who lived away from their native land. This could be because they chose to, or they were sent away and denied permission to return. The term of exile could also describe the sentence itself.

Among the Time Lords of Gallifrey, exile was often viewed as a worse punishment than death due to the close bond between a Time Lord and their homeworld; it was thought that "permanent exile was death of the soul". (PROSE: Warmonger)
