" With her mind, Arya tells Eragon that she has been ferrying Saphira’s egg between the elves and the Varden, in the hopes that it might hatch for one of their children. However, during her last trip, she was ambushed by Durza and forced to send the egg elsewhere with magic, which is how it came to Eragon. Now Arya is seriously wounded and requires the Varden’s medical help. Using mental images, she shows Eragon how to find the rebels. An epic chase ensues. Eragon and his friends traverse almost four hundred miles in eight days. They are pursued by a contingent of Urgals, who trap them in the towering Beor Mountains. Murtagh, who had not wanted to go to the Varden, is forced to tell Eragon that he is the son of Morzan. "
