Saphira

When she was sufficiently recovered, Saphira walked forward and passed between two giant, moss-covered oak trees and so crossed into Du Weldenvarden on foot. The elves had made it impossible for anyone or anything to enter the forest by means of magic, and since dragons did not rely upon their bodies alone to fly, Saphira could not enter while in the air, else her wings would fail her and she would fall from the sky.
