" He stole another dragon—whom he named Shruikan and forced to serve him through certain black spells—and gathered around himself a group of thirteen traitors: the Forsworn. With the help of those cruel disciples, Galbatorix threw down the Riders; killed their leader, Vrael; and declared himself king over Alagaësia. In this, Galbatorix was only partly successful, for the elves and dwarves remain autonomous in their secret haunts, and some humans have established an independent country, Surda, in the south of Alagaësia. A stalemate has existed between these factions for twenty years, preceded by eighty years of open conflict brought about by the destruction of the Riders. "
