Adept was a Sith rank during both the Old and New Sith Wars, similar to Sith Acolyte. One example of Sith adepts during the Republic Dark Age were the Unifiers of the Dyarchy. The Brotherhood of Darkness trained them in the Dathomir Academy and Iridonia Academy. It was later used in the One Sith as an alternate form of address for acolytes.
