- Fan Nickname: "Galby" for King Galbatorix, and "CP" for the author.
- Follow the Leader: One of several young adult novel series which picked up speed after the success of Harry Potter.
- I Knew It!: Most of the fandom accurately predicted that Brom is Eragon's father and that the green dragon egg would hatch for Arya. It also wasn't a big surprise to many that the Vault of Souls contained Eldunari despite Oromis and Gladers' protestations that this wasn't possible.
- Jossed: Christopher Paolini officially stomped on the theory that the sapphire in Aren is the Eldunari of Brom's dragon.
- Limited Special Collector's Ultimate Edition: Each book has received a "Deluxe Edition" reprinting which usually includes some goodies like drawings from cover artist John Jude Palancar and/or Christopher Paolini himself. Deluxe Editions are usually released a year after the original publication and can be distinguished by a ring of gold around the cover. Eragon and Eldest were reprinted together in an Omnibus edition which was so big it could be used as a bludgeon.
- Sequel Gap: The Fork, the Witch and the Worm was released on December 31st 2018, more than seven years after book four, Inheritance, was published (November 8th 2011).
- Shrug of God: If anything even remotely related to a theory for an upcoming book is mentioned to Paolini's face or asked in an interview, he always responds with "No comment."
- What Could Have Been:
- Christopher Paolini originally intended Eragon to have simply blessed Elva as a baby, but found out after the publication of Eragon that he had made some grammatical mistakes himself in creating the ancient language, resulting in Eragon's wording being "may you be a shield from misfortune". Rather than simply correct the error, he decided to make it a plot point in future books.
- In early drafts of the final book (back before it was split into two books), Roran ended up becoming king of the Broddring Empire.
- Arya was going to leave Alagaesia with Eragon and Saphira and Islanzadi survived; as such, Arya never becomes queen of the elves. This is a particularly notable example, as in Eragon's Guide to Alagaesia, which was published around two years before Inheritance in 2009, Islanzadi is said to have survived the Rider War, so Paolini clearly changed his mind about that between publications.
- Originally, Murtagh and Thorn would've died in the final battle, but Paolini let them live as he ultimately felt it would unfair to them after how much they suffered (and most fans would agree).
- The Inheritance Cycle was originally the Inheritance Trilogy (and is referred to as such in some early publications and by the film adaptation), until Paolini decided the plot was too large and complicated for one book and so split the final book into two novels, Brisingr and Inheritance. And he may have plans to write a fifth book as well.
- The Wiki Rule: Inheriwiki.
- Word of God: Christopher Paolini answers a lot of questions about the Cycle, mostly in interviews. Just look at all the examples throughout the pages for this series.
- Write Who You Know: The behaviors and mannerisms of Angela the herbalist were based largely on Christopher Paolini's sister, Angela.
