Most Devoted One was the title given to the seniormost member of the Acolytes of the God-King, the priests of the Salbin faith and personal servants of the Exoi God-King. The Most Devoted One was leader of the Acolytes and counselor to the God-King, and appointed all Acolytes of the Many Truths, Glorious Presence, and Most Blessed Flesh.
The Most Devoted One wore rainbow-colored robes. The Exoi appointed to that rank was named by the God-King personally, though in the final centuries of the monarchy, when the God-Kings were largely mentally incapacitated, the Acolytes of the Most Blessed Flesh collectively voted one of their own into the rank. Upon promotion, the new Most Devoted One renounced his name and was referred to by title exclusively.
The last Most Devoted One cared for God-King Chohwelk VII, unsuccessfully attempting to get the indolent Chohwelk to mate and continue the bloodline. He was killed in 155 ABY by Tarzg Sav'lir after Rin Sakaros euthanized Chohwelk, and with no God-King left, there was no one to appoint a new Most Devoted One; the title passed into history.
