Yazuac was one of the many villages obliterated by the Broddring Empire during the Northern Massacres. It was completely wiped out by Urgals, held under control of the Broddring Empire by the Shade Durza. What made Eragon most angry was the baby on top of the pile of the dead, an Urgal spear embedded in its side: however, he then killed a raven that tried to eat the baby with his bow, despite the fact that it was not doing anything truly wrong. It was also this anger that allowed him to first use magic.
It was populated by around two hundred people at its peak and was bordered by the Ninor River.
