Gríma, commonly called Wormtongue because of his evil ways, was the counsellor of King Théoden and a traitor. He truly served Saruman, and through this partnership Saruman learned much of the thoughts of Théoden. This also served as a way to weaken the old king, for Wormtongue often gave ill counsels which would go only to benefit Saruman. After the revival of Théoden Wormtongue fled to Isengard, and there he threw the Seeing-stone out of Orthanc. He later accompanied Saruman to the Shire, where he killed the Wizard, and was then slain himself.
