Murtagh Morzansson

Murtagh Morzansson is a male human who was at one point Eragon's ally, but was enslaved by Magic and forced to fight for the Broddring Empire. He was the son of Morzan, the man who betrayed the Dragon Riders to Galbatorix and helped destroy them; and Selena, Morzan's Black Hand and the most feared of all the Broddring Empire's spies and assassins. He was the eldest of Selena's two children, the other of which is Eragon Shadeslayer: consequently being Eragon's half-brother and Roran Stronghammer's first cousin. He was a fiercely loyal companion and an accomplished swordsman. He wielded a hand-and-a-half sword and later, Zar'roc, which he stole from Eragon, a yew bow, a dagger and a white horn with silver fittings. He rode a warhorse named Tornac, which was named after his old swordsmanship tutor. During Eldest, one of King Galbatorix's Dragon eggs hatched for Murtagh and he named the red Dragon Thorn. He was the main antagonist in Eldest.
