The Dragons of Inheritance
Saphira
Saphira is Eragon's dragon. We first met her in Eragon, the first book in the Inheritance Cycle Saga. Saphira Brightscales, as she is known, is a blue dragon who hatched out of an egg that Eragon found when he was just an insignificant farm boy. She then hatched out of the egg, surprising Eragon, who touched her, therefore receiving the unique mark on his hand. Like all dragons, Saphira hates being separated from her Rider.
Glaedr
Glaedr belongs to Oromis. The gold dragon is extremely loyal, and, I might add, has said quite a few memorable quotes in the Inheritance series. He has given some good advice to Eragon in the past.
Shruikan
Shruikan is a black dragon that joined Galbatorix. His Rider was murdered by Galbatorix and Shruikan was taken by Galbatorix to be his own. The dragon did not take very kindly to Galbatorix, though, and was forced to swear loyalty to him against Shruikan's will.
Thorn
Thorn is the dragon of Murtagh, Eragon's half-brother. He is red and was forced along with Murtagh to swear loyalty to King Galbatorix. Their oaths of loyalty will be undone if their true names change, though.
Firnen
Firnen is Arya's green dragon. FIRNEN IS THE BEST DRAGON EVER!!!! In my opinion, at least. I like Firnen! DID YOU KNOW I LIKE FIRNEN???? GREEN DRAGONS ARE SO SUPER AWESOMELY EPIC AND STUFF
