How we cite our quotes:
Brom's eyes grew hazy […] "The sea is emotion incarnate. It loves, hates, and weeps." (23.5)
How poetic. For Brom, his explorations of the sea allow him to share his intense emotional experiences with Eragon. Eragon, through Brom's words, is allowed to explore this wild frontier, and we as readers are provided with sense of awe and adventure. We could write out this whole quote for you, but this is such a beautiful passage that you've just gotta read it for yourself.
Eragon […] eagerly began exploring Teirm. For hours he wandered the streets, entering every shop that struck his fancy and chatting with various people. (26.3)
Eragon is just an explorer at heart. It's one of the things we really love about him. Maybe you know people who, on vacation, stay inside their hotel rooms and watch TV all day. Okay, sometimes we're guilty of that, too. But travel is about new people, new sights, and new experiences. Even though it can be scary, it's an unmatched opportunity to learn that Eragon takes full advantage of.
Across the plains, sprawled the forest Du Weldenvarden. Like the Beor Mountains, its eastern end was unmapped. […] [I]ts heart lay mysterious and unexplored. (28.54)
Unlike our world, which is pretty much mapped out, save for the most remote corners, Alagaësia is still a wild place that has yet to be fully explored. Such mysteries provide an excellent chance for explorers, like our pal Eragon, to pursue adventure.
