"Game of Thrones" Season 5 premieres on HBO on Sunday, and we know the season will follow some old favorites like Jon Snow, Arya Stark, Daenerys, the Lannisters and Sansa Stark and also will introduce viewers to the land of Dorne. But series creators David Benioff and D.B. Weiss promise some interesting changes, and even readers of George R.R. Martin's "A Song of Ice and Fire" novels are unsure where the story is going. We're here to offer some bold predictions that will surely go wrong.

Warning: "Game of Thrones" spoilers ahead.

Someone Will Die

This seems obvious, right? While it's likely that another major character will be killed -- this is "Game of Thrones," after all -- there's interesting speculation about who will die. Arya will begin her training at the House of Black and White, which means we'll get a look at the Faceless Men. Considering Season 4 featured a cold-blooded Arya, it's likely she'll begin her career as an assassin. There also are battles teased in the Season 5 trailers, so you can add those people to the deceased column, but what about major characters?

Winter Is Coming has some interesting picks for character deaths. In terms of streamlining storylines, killing Loras Tyrell would make sense. Jorah and Bronn are other likely candidates for death. While Jaime's fate in "ASOIAF" is uncertain, I think he'll be safe for now. The Lannisters are going through a rough patch and the focus will be on Cersei's downfall and "walk of shame." Jaime is headed to Dorne and we're going to learn a lot about the Sand Snakes, the Martells and Myrcella Baratheon.

Brienne's story also has changed drastically now that Lady Stoneheart is out of the picture, so she's a good candidate for a character who's alive in the books but dies in the show, as Martin has teased. Despite Brienne looking like a strong contender to die, there is speculation that she'll meet an important character. That seems to have some truth to it based on the episode 2 synopsis. If that's the case, that would make her a more important character than she is in the books.

Two Books, One Season

It's likely that "Game of Thrones" will be way ahead of Martin by the time Season 5 wraps up. "A Feast for Crows" and "A Dance With Dragons" -- the fourth and fifth novels in what Martin plans as a seven-book series; the sixth still is being written -- are basically one giant book and the HBO show has already trimmed a lot of fat from "ASOIAF." Tyrion will be way ahead of where he is in the books, while Bran is on the sidelines for this season after flying through his storyline in Season 4. There also are small scenes -- like the look at the White Walkers and their city last season -- that will propel viewers ahead of readers. Based on the trailers, Sansa is coming back to Winterfell, which has yet to happen in the books. Some stray storylines from the two novels will appear next season, but there will way more uncharted territory.

How Will 'Game Of Thrones' Season 5 End?

The season hasn't even started, but we're talking about the finale? Judging by the trailers, Stannis and the Boltons will battle, there will be dragons, and Jon Snow will take control of the Wall. Daenerys will struggle to keep her rule and face opposition from the Sons of the Harpy, and Drogon will be set free. There also will be two weddings, but -- again -- it's "Game of Thrones," so someone will die. It's likely to be Hizdahr zo Loraq, Dany's husband, who will drawing the short straw. The big moment of Season 5 probably will be the "death" of Jon Snow." "ASOIAF" readers assume he's still alive and the show could see him become Lord Commander and later get killed. They could save his revival for next season or have Melisandre bring him back to life, as io9 speculates will happen.
