Iceblades

The warriors known as the Iceblades were fanatically loyal to Morathi - but then, they had no choice. Each was a handsome noble, seduced from his proper loyalties by Morathi's handmaidens and lured away to Ghrond. Once within the Tower of Prophecy, the lies of luxury and bliss fell away, replaced by a reality in which icy poisons stripped away the mind, leaving the victim little more than a puppet longing for instruction. Only Morathi and her most favoured handmaidens knew the words that compelled the Iceblades, for they jealously protected the thrill of such total control.
