After successfully evading an Urgals ambush, Eragon is adopted into the Ingeitum clan and sent to Ellesmera to finish his Dragon Rider training, but danger and betrayal continue to follow him.

Long before the SandWing and the Dragonet Prophecy, Darkstalker, half NightWing and half IceWing, is hatched under the three moons--born into a divided heritage, he is destined to become the most powerful and dangerous dragon Pyrhhia will ever know, and it will take the combined efforts of a SeaWing named Fatham and a NightWing seer named Clearsight to come up with a way to save all the kingdoms from his anger.
