Grey Worm agrees to disseminate the instructions to the other Unsullied, but chooses to keep his. Upon reporting his election to Daenerys, she finds his name and its associated practice– given to him by the Good Masters to remind him that he is vermin– distasteful, and tells him that he and all Unsullied may use their original names or chose new ones they like. Grey Worm is selected, though it is not established how. Season 3Īs per Daenerys's instructions, the Unsullied officers select their own leader to act as their official commander, reporting directly to her. Once released, Grey Worm, like all his brethren, chooses to fight for Daenerys as a free man. He is released from slavery after Daenerys Targaryen buys all the Unsullied in the city and has them put all slave owners in Astapor to the sword and release all slaves. He has no memory of his life before being an Unsullied. It later is revealed that he is originally from the Summer Islands and was taken by the slavers in a raid as a baby. Grey Worm was originally a boy taken into slavery by the Good Masters of Astapor, an oligarchy of slave-traders dedicated to the training and commerce of Unsullied, warrior-eunuch slaves trained into absolute obedience since early childhood.
