Life debt/Legends

A life debt is a tradition practiced by many honor-bound cultures in the galaxy, including the Wookiees, the Gungans, and the Srrors'tok. In these cultures, if someone's life is saved by another (even an outsider), honor demands that the person saved serve their savior as though their life belongs to the other. How strict this bond depends on the culture people involved. Among the Gungans, the bond is fairly loose, while among the Wookiees, the life debt is one of the most solemn possible pledges. Some unscrupulous recipients of a life debt have taken advantage of their position by enslaving and otherwise mistreating the unfortunate person sworn to their service.

Famous life debts include Jar Jar Binks' life-debt to Qui-Gon Jinn, and Chewbacca's life debt to Han Solo (which later expanded to his wife Leia Organa Solo, his children Jacen, Jaina, and Anakin, and his brother-in-law Luke Skywalker.)
