Grey Worm is the commander of the Unsullied, the warrior-eunuchs of Astapor whose reputation for combat is without equal. Like all Unsullied, Grey Worm's castration as a boy resulted in changes to his body's hormones, so he is smooth-cheeked with absolutely no facial hair. Grey Worm is a loyal man that would do anything for Daenerys Targaryen since she helped him be free from being a slave. Grey Worm struggles with being social with other people to do being a slave all of his life and he still does not understand how to be "normal".
