5 Popular 'Game of Thrones' Theories You Need to Know For Season 8

The final season of "Game of Thrones" is upon us and winter is finally here.

It feels like forever since the HBO fantasy drama graced our screens and the anticipation for Season 8 has been building ever since. As in the past, the final season of "Game of Thrones" has been shrouded in secrecy to avoid any types of spoilers getting out, with the trailers barely giving anything away.

Thankfully, we are now only one sleep away from the premiere.

The eighth season will sadly have the fewest amount of episodes with only six, however, Episodes 4, 5 and 6 will be well over an hour.

While the big question now is how will it all end, we're also dying to know who will end up on the Iron Throne, the identity of the "Prince That Was Promised" and more about the Night King's backstory.

If you're a "GoT" nerd like us, then you know Reddit is a haven for "Game of Thrones" theories. And because we're nice and understand that you are stressed out about the new season, TooFab took a deep dive through Reddit and "Game of Thrones" history to get you pumped for this Sunday.

Here are five very important theories every Westerosi needs to know:

Many predict that Cersei Lannister (Lena Headey) will die in the series, but how she will be killed is the ultimate question. The valonqar theory is not only the most popular, but it's also one of the more plausible theories.

If you recall, in Season 5 Episode 1, a young Cersei visited a witch named Maggy the Frog in a flashback sequence. In the memory, Cersei received her prophecy from Maggy, who told her all of her children will die. "Gold shall be their crowns and gold their shrouds," she said. (R.I.P. Marcella and Tommen, but we're not really hoping Joffrey is resting in "peace.")

However, in the "Game of Thrones" book "A Feast For Crows," Maggy added, "And when your tears have drowned you, the valonqar shall wrap his hands about your pale white throat and choke the life from you." Cersei learned that "valonqar" is High Valyrian for "little brother." If this theory is true, this means either her twin brother Jaime (Nikolaj Coster-Waldau) -- he was born after her -- or Tyrion (Peter Dinklage) would be the one to kill her.

So how likely is this theory? Well, think about where we last left Cersei and Jaime. The characters have been through it all and Jaime, shockingly, has stood by Cersei's side during all of her crazy antics. But if you recall, at the end of Season 7, Cersei told Jon Snow (Kit Harington), Daenerys Targaryen (Emilia Clarke) and the gang she would send the Lannister army to come and help the North fight the Army of the Dead. However, after they left, Cersei told Jaime she was lying. Jaime seemingly decided to leave because he promised to fight for the living. (That's our Jaime!)

Plus, don't forget that Jaime is known as the Kingslayer after he killed Dany's pops, the Mad King, when he wanted to burn down King's Landing. And many have argued Cersei became the Mad Queen when she burned down the Sept of Baelor in the Season 6 finale.

Another thing we'd like to point out, some Reddit theorists and "GoT" fans alike hope that Arya Stark (Maisie Williams) will be the one to kill Cersei since she is one of the many on her "list" of names. Since Arya is a Faceless Man, she could easily take Jaime's face and kill Cersei.

A very popular fan theory is that Brandon Stark (Isaac Hempstead-Wright) is actually the Night King. There are multiple variations to this one, many involving time travel, but basically, it goes like this:

With his special abilities -- he's a warg, has prophetic dreams and greensight -- Bran is the key to everything. Future Bran learns of the Great War and the Army of the Dead and will travel back in time in order to stop the Night King. As Reddit user turm0il26 writes in a very detailed theory, "Bran believes he is eventually (with more knowledge) going to be able to rewrite history and that's why he decides to go back and stop the Night king several times, but fails every time, ending up fulfilling the timeline-circle and taking the identity of the Night King himself."

Bran's "failures" are present in many Reddit users' theories. There are three.

• In his first attempt, tum0il26 explains, Bran tried to warn the Mad King about the White Walkers' looming threat and told him to use the wildfire to destroy them. When we hear the Mad King yell, "Burn them all" -- as seen in Bran's flashback in Season 6 Episode 6 -- it's actually Bran who whispered the words to the King and he was repeating them. Although Bran was referring to the Army of the Undead, the Mad King went insane and instead tried to burn King's Landing.

• The second time, Bran went back in time and became Bran the Builder, where he built The Wall to protect Westeros from the White Walkers and created Winterfell, along with the words "There must always be a Stark in Winterfell".

• The third and final time, Bran returned to when the Night King was created and warged into the human that became the Night King and attempted to stop the White Walkers being created.

We will have to just wait and see whether this will come true, but Jon Snow having to kill his brother does sound like "bittersweet" ending George R.R. Martin has promised.

As we know, Jon Snow is actually Aegon Targaryen, the son of Rhaegar (Dany's brother) and Lyanna Stark (Ned's sister). However, there are theories that Tyrion also has a hidden parentage and is the son of Aerys Targaryen (a.k.a the Mad King, Dany's father) and Joanna Lannister, Tywin Lannister's wife.

Back in Season 2, Daenerys visits the House of the Undying while in Qarth. In the books, it is here that Dany has a vision of Rhaegar telling her "the dragon has three heads," which is the Targaryen house sigil.

In "GoT" history, the first Lord of the Seven Kingdoms and King of Westeros, Aegon Targaryen, a.k.a Aegon the Conqueror was said to have conquered while riding a dragon, alongside his two sisters on their dragons. Therefore, the prophecy has been interpreted to mean that Daenerys must have three dragon riders before she herself can take the throne.

If this theory is proven true, it would make sense that Jon and Dany would be the first two riders. And Tyrion could be the third. In Season 6, Tyrion confronted the dragons in the tombs of Meereen and remained unscathed and in the books he was described to have been always very fond of the fire-breathing creatures. Most importantly, Twyin often referred to Tyrion as "not his son" throughout the series.

A Reddit user also pointed out that Dany, Jon and Tyrion all lost their mothers to childbirth. This can't just be a coincidence, right?

Don't forget though, one of Dany's dragons, Viserion, is now dead or rather "undead" so someone might possibly have to ride an ice dragon -- unless someone like Melisandre were to bring Viserion back to life, but that's a whole other conversation.

Ahh Gendry, one of our favorite characters that we think is often underrated. Luckily, this all might change. We know Gendry as one of Robert Baratheon's bastards. However, there are many who think there is much more to Gendry's story, which we might learn in Season 8. Some people believe that Gendry, like Jon, isn't actually a bastard after all, but the first born child of Cersei Lannister.

Back in Season 1, when Bran was in his coma, Cersei told Catelyn Stark about her first child who died in childbirth. She said the infant was born with black hair. We always thought this was just a way to show Cersei's three children with Jaime, who were born with blonde hair, were not legitimate. But the big question is, if this black-haired babe is actually Gendry and didn't die, how did the child get away?

Reddit user u92beck proposes Jaime faked the baby's death because he wanted all of Cersei's children to be his and only his. The user writes, "Jaime was so in love with Cersei, and jealous of her relationship with Robert (it seems she was in love with both Jaime and Robert at the time) that he decided to get rid of the child that they were bonding over to drive them apart. He switched the baby with one that was already dying of fever and planned to either kill or get rid of the real baby. Either he or an accomplice (possibly ignoring Jaime's orders to kill the baby) gave the baby to the blacksmith with money to keep the baby safe."

The person also pointed out another interesting clue. During the same conversation Cersei had with Catelyn in Season 1, as referenced above, Cersei described the black-haired infant as a "fighter." And in Season 7, Gendry described himself as a fighter. It could just be a coincidence, it's all very interesting.

Most importantly, if this all true and Gendry is a true born son of Robert and Cersei, he would have as legitimate a claim on the Iron Throne as Jone.

Also in the novels -- without spoiling too much -- another very legitimate claim to the throne is switcharoo'd at birth.

Another popular theory involves Azor Ahai, "The Prince That Was Promised," a prophesized hero from the Lord of Light. If you recall, Melisandre (Carice van Houten) believed Stannis Baratheon to be the chosen one, but after his death and after she brought Jon back to life, the Red Priestess has alluded Jon will be Azor Ahai and that Daenerys Targaryen will have a role to play as well.

Fans have discussed many options over the years as to whom the prophecy refers -- Beric Dondarrion, Jaime Lannister and Rhaegar Targaryen have even been suggested in the conversation -- but the two most likely and popular candidates are Jon and Daenerys.

For reference, the prophecy states that "when the red star bleeds and the darkness gathers, Azor Ahai shall be born again amidst smoke and salt to wake dragons out of stone." The prince was said to have a burning sword of flames, named Lightbringer, which he formed while sacrificing his wife, Nissa Nissa. The last part seems particularly savage, but let's be real, it would be shocking if both Jon and Daenerys survive the final season (we're still secretly hoping though).

Below are both arguments put in simple terms. There are many interpretations that exist for this prophecy.

Jon Snow is Azor Ahai:

• "Born again amidst smoke and salt": "Smoke" is one of the trickier parts for Jon's case. We think the "smoke" could represent the fact that his birth was a secret. Some also think the "smoke" could be from Jon's wounds when Melisandre brought him back to life. "Salt" could refer to Lyanna's tears.

• "Wakes dragons out of stone:" Jon and Co. are mining the dragonglass from Dragonstone. Also, Jon is Targaryen after all and has "dragon blood."

• "Lightbringer:" Jon will have to sacrifice Daenerys. He also has a Valyrian steel sword "Longclaw," so some people suggest he might already have the sword.

Daenerys Targaryen is Azor Ahai:

• "Born again amidst smoke and salt": Dany was born in Dragonstone. The "salt" could refer to either her tears she cried when Khal Drogo (Jason Momoa) died or the "salt" from the ocean. People suggest the "smoke" refers to when Daenerys came out of Drogo's funeral pyre unscathed in the Season 1 finale.

• "Wakes dragons out of stone:" She hatched or woke three dragons from their eggs, which were made out of stone and thought to essentially be fossils.

• "Lightbringer:" Dany will have to sacrifice Jon or possibly a dragon. Some fans even think her dragons can be considered to be her "burning sword." Also, some even argue Dany has already made her sacrifice by giving her dragon to the Night King for Jon.

"Game of Thrones" Season 8 premieres Sunday, April 14 at 9 p.m. ET on HBO
