The identity of who dies at the end of Brisingr
In the same interview that he announced Book IV, Christopher Paolini said, “Since I split Book III [Brisingr] into two books, I pondered for a long time on how to end Book III. The answer came up as the same solution I used to begin Eldest: with the death of a major character. I’m not going to say who…”
Obviously, this character is one that everybody loves and hates to have die. The options are fairly simple: Nasuada, Orik, Oromis and Glaedr, and—by an extremely complicated theory—Saphira.
Nasuada is the most likely. If she dies, then the Varden need a new leader for Book IV. The leader could be Elva or, more likely, Eragon.
Orik is also likely, though not as likely as Nasuada. The dwarves need a king, and Orik is the only option right now. So no, Orik will not die.
Oromis and Glaedr are right up there with Nasuada. It has been repeated throughout Eldest that they will die sometime, so why not at the end of Brisingr? The only theory against this is that Glaedr will appear on Brisingr’s cover, and it’d look bad for the cover character to die. However, considering Paolini’s plot, Oromis and Glaedr are extremely likely.
Please take the time to read my Fate of Saphira thread before looking any further.
Now, it is very likely that Saphira will be captured before the end of Brisingr. Why, you ask? In Eldest, Eragon murmured a spell: “Brakka du vanyalí sem huildar Saphira un eka!” Translated, “Reduce the magic that holds Saphira and me!” However, the word Huildar can be translated into two words: “Holds” or “Binds”. As he did with Elva, Eragon could very possibly have placed a curse on somebody instead of a blessing. This curse, however, would be directed at Saphira.
A completely different theory is in line for how Eragon and Saphira separate to begin with, but let me just narrow it down to Eragon getting awful mad. Saphira, heartbroken, feels she has no choice but to turn herself in to Galbatorix. This could very well take place before the end of Brisingr.
But, her dying at the end? That’s going too far. The only way for her to die is to save Eragon from dying, and Eragon would be saved from Galbatorix, who he would kill with that moment. That’s one too many people dying, and Paolini has said that only one person will die.
So, Saphira might be in captivity at the end of Brisingr, but we’ll have to wait for Book IV to see her die.
