Slavery

"Kyrenthea's laws protect all her kin, including the slave."

- Asra T'sael to Vixannis Slavery is a system under which people are treated as property to be bought and sold, and are forced to perform various kinds of work. Slaves are typically captured as either debtors to society or in wars and raids, and some are poor and are sold into slavery by either their own parents or themselves.

Slavery has officially been outlawed by many surface nations, though continues to exist. In Drow society, slavery is used instead of a prison system with many criminals serving nobility and regents for an determined amount of time designated by their purchaser.

Black Marches
Even before the Divine Marches, slavery was a common practice in Taranost. (TBA)

After the Divine Marches and the rise of the Holy Seladen, slave laws were placed in the Black Marches that turned the practice into more of indentured servitude.
