Once Eragon begins to receive training from Brom, his lessons fall into two categories: magic and combat. Because of this, two associated motifs frequently appear in the novel—swords and words. They both speak to the theme of the Pursuit of Power. In this context, words refer to the ancient language of magic. As Brom explains the concept, this elemental language describes not only the superficial characteristics of a thing but its essential nature. As a result, using the arcane word for “fire” will summon fire itself. Words become a handy part of Eragon’s arsenal as he uses elemental words to battle his enemies on multiple occasions. The knowledge of magic words is so highly prized that the Twins challenge Eragon to prove his magical abilities merely so they can steal more words from the secret language of spellcasting.

The use of swords is just as important in wielding power. The provenance of swords gives them quasi-mystical properties too. When Brom feels that Eragon is ready, he presents him with a sword, and it has a name—Zar’roc. It was forged by elves, which gives it exceptional qualities as a weapon. Further, it once belonged to the villain, Morzan.
