Indenture is a Banu practice in which another being is purchased for a limited-term service contract. Most Indentured Banu are children who have been put on the market to be sold to an appropriate Souli, where they will be taken on as an Apprentice and trained in a new skill in exchange for room and board. Upon adulthood, a successful Indentured Apprentice will be granted full membership in their Souli. Adults in the Banu Protectorate may sell themselves into Indenture to pay off a debt, learn a new skill, or for a variety of other reasons. Prisoners can also be sold to Indenture Soulis for a profit.
