Slavery has a long and unusual history among the Seanchan, with slaves having the ability to rise to positions of great power and open authority, including authority over those who are free. An example of such a position is so'jhin.
Da'covale traditionally wear nearly transparent white robes. When outdoors, these are usually covered by outer robes of thick white wool. Higher ranking da'covale, such as so'jhin, do not wear these robes, and shave half of their heads.
