The main conflict is the fight at Farthen Dûr.Urgals, under the command of the shade Durza, had been marshaling in secret in Ithrö Zhâda, a hidden fortress within the Beor Mountains (and once an old Dwarven city known as Orthiad), for months prior to the assault. Luckily, the Varden were able to anticipate and prepare for the attack, thanks to a message received by the dwarves. The Varden had their women and children evacuated to the surrounding valleys with guides to take them to Surda, in case the Varden were defeated. However, some of the women such as Arya and Nasuada stayed behind and fought in the battle anyway. Ajihad also sent messengers to Surda and the elves in Du Weldenvarden, so that if the Varden were defeated, they would not be caught by surprise.
The point of view is Third Person Limited because you only know Eragons thoughts but the exception is that Saphira talks to him through his thoughts.
