As a Dragon Rider, Eragon discovers he has magical powers and abilities. Brom helps him hone these skills. Eragon learns that using the right words from an ancient language allows him to kill, heal and otherwise manipulate his situation. He communicates telepathically with Saphira. The two have a magical synergy that lets them combine their powers for added strength.
After Eragon discovers he can communicate telepathically with animals besides Saphira, Brom informs him he can do the same with humans if he trains his mind. Brom suggests that with the right instruction, anyone can talk to someone else mentally. Brom says Eragon’s magic is not like that of a Shade, who allows spirits to live in him. Eragon also isn’t like regular witches, wizards or magicians who rely on spells and potions.
Brom offers words of warning along the way. For example, he urges Eragon to use discernment and caution when infiltrating the thoughts of another human. (Eragon does this to Arya when she’s comatose in an effort to save her life.) Brom also instructs the boy not to attempt certain feats, such as raising another human from the dead. He says there is an abyss beyond life where magic means nothing and the Rider’s powers will fail him. Saphira, too, warns that magic can yield unexpected results when the ancient words are combined in new ways. She reminds Eragon that magic can protect him where speed and luck fail.
Eragon thanks the gods, known and unknown, when he finds Saphira healthy one morning. Brom says some believed the Dragon Riders had the powers of a lesser god. After his uncle’s death, Eragon demands that the god who did this would show himself. The slaughter of the townspeople at Yazuac makes him ask himself what a person’s existence is really worth if life can end this way.
Eragon has a (correct) premonition that his uncle will die. As he grieves and wonders what to do, Saphira tells him his heart can be his only true guide and that its desires must lead him. His heart leads him to exact revenge on the murderers, and that becomes the focus of his quest. Brom says Eragon “deserves” revenge for his uncle’s death.
A witch named Angela tells Eragon his fortune, only after she’s warned him of the dangers and he’s consented. She uses the knucklebones of a dragon to read his future, saying that unlike tea leaves, crystals or divining cards, they have true power and do not lie. In the midst of her reading, Eragon is thoroughly convinced of the woman’s power and ability. She tells him he’s one of the few who can truly choose his own fate. She sees a terrible omen that indicates he must leave his land. Angela’s werecat offers Eragon a further warning: If his power ever seems insufficient, he is to go to a certain rock and speak his name to open the Vault of Souls. Before Brom dies, he touches Eragon’s forehead and gives him his blessing. He also tells him some powerful ancient words that he can use when he’s in great need. Brom’s death further proves to Eragon that Angela’s fortune telling was real and correct.
At a strange, rocky mountain range, Brom tells Eragon that people in nearby towns pray to the rock formations and engage in cruel religious practices. They drink human blood and make flesh offerings. Many priests have severed their own body parts, believing the more bone they give up, the less they’re attached to the mortal world. Eragon kneels, bows his head and pays homage to a cathedral’s physical building, but the narration notes that he does not pray.
The Varden have magicians that probe people’s thoughts before they’ll let them into the city. Preparing to test Eragon’s magic skills, they draw a pentagram on the ground.
During a bad dream, Eragon prays for someone to lift him out of his nightmare. He says no one comes to guide him. Then he hears the voice of the Mourning Sage. The Sage promises to help Eragon if he will follow.
Shades, such as Durza, practice the most unholy magic after necromancy. Angela says ordinary sorcerers are just like her; they use magical strength to control spirits and the spirits’ powers. Shades, however, relinquish all control and allow their bodies to be controlled by spirits to achieve the greatest power.
The story also contains references to bad or “black” luck.
