An Unsullied chosen as commander of his company by the casting-stones his brothers threw the day they marched free of Astapor with the dragon queen. Once a slave of Astapor, drilled from infancy in the discipline of the Unsullied at the cost of his manhood, he kept his slave-name Grey Worm after Daenerys broke his collar; he has said that of all the new names his brothers chose he found his the luckiest, for the worm a slave-master had bid him be must crawl in the dirt forever and so could never fall further.
