SPOILER ALERT!
The new season of Game of Thrones started last night and like any diehard Thrones fan, it is now a good time to speculate on what is going to happen during this season.
#1. The Wall is Coming Down
The Wall is magical, we know this because Benjen Stark cannot pass beyond the Wall due to the Wall's magical properties.
According to legend the Wall cannot be destroyed except by the Horn of Winter, which is also a magical object. When the horn is blown it is supposed to cause vibrations within the ice that will cause the ice within the Wall to shatter. (This is similar to the Biblical story of horns being used to cause an earthquake in the city of Jericho - Joshua 6:20.)
Sam Tarly way back in second season found a horn along with a stash of dragonglass. Hint hint. The horn is likely currently at Castle Black.
#2. Jon Snow is going to Dragonstone and will meet Dany and Tyrion
It will not be the first time Jon Snow and Tyrion have hung out together. Both shared a friendship during Tyrion's visit to the Wall in Season 1. But it will be the first time Jon has met Dany, and this grouping of all three together will put all three Targaryen's on the same island together at the same time.
Jon Snow will go to Dragonstone after he receives a raven from Sam Tarly, telling him that there is a giant amoung of dragonglass on the island of Dragonstone. If he is smart, Jon will also try to convince Dany that the real threat is in the north and that the White Walkers are coming.
And if we are lucky, Jon will get attacked by fire or dragonfire, and we will learn that he (and possibly Tyrion too) are all immune to fire. Dany will then realize that all three of them are Targaryens.
The end game of this will be Dany, Tyrion and Jon all riding dragons together.
#3. Cersei will ally herself with the Starks, but secretly plot to kill them
In the ever-shifting alliances of Game of Thrones, Cersei needs more allies. Jon Snow / Sansa Stark will offer her a deal to end the war in an effort to get more people to help fight the White Walkers. But Sansa will know that Cersei is not to be trusted.
During this Cersei will take her army north, including her beast-zombie the Mountain.
When Cersei does strike and betray them, Jaime will have to choose between letting her kill thousands of people - or killing Cersei. But the Mountain will stop him...
Cersei could eventually get captured by the Night King and become a White Walker -
the Night Queen.
#4. Brienne and the Hound killing Wights and White Walkers
The Hound (Sandor Clegane) is heading north and now knows the Fire God is real. He has also seen a vision of the undead wights in the north, and knows they are heading south. Clegane vs Wights? Bring on the wights because Clegane is going to be awesome at killing them.
There is only one problem, Clegane doesn't have a Valyrian steel sword and will break any weapon he currently has when fighting a White Walker.
Enter Brienne - who does have a Valyrian steel sword, Oathkeeper. And she is equally awesome in combat as the Hound.
Now put those two together, fighting back to back vs a horde of White Walkers and wights. That is a fight worth watching!
#5. Sam Tarly will become a Wizard
Magical learning is one of the things maesters sometimes get into while at the Citadel. In the books Sam meets other students at the Citadel who have learned that magic has come back into the world with the birth of dragons, that dragons essentially emanate magical power that can be tapped into. Sam will realize that what Jon Snow and everyone else really needs is not a maester, but a wizard.
Which will fulfill what Sam said back in Season 1: "I always wanted to be a wizard." to which the other guys laughed, because at the time it was a silly idea.
And there is a line in a later season in which Gilly says to him: "You are like a wizard."
Bonus Prediction #1. Gendry will forge a Valyrian steel sword for Arya
The smith who taught Gendry is the same smith who made Oathkeeper and Widow's Wail by melting down Ned Stark's huge sword Ice. This means that smith knows how to melt down and reforge Valyrian steel.
Which means Gendry probably knows how to reforge Valyrian steel.
Add dragonfire to this mixture, and Gendry might someday be able to make
new Valyrian steel blades, without the need to melt down old Valyrian steel blades.
Eventually Arya is going to realize the real threat is also in the north, and her sword Needle will end up breaking if she tries to use it against a White Walker. At some point she and Gendry will meet up, and Gendry will make her a new sword which will be useful against White Walkers.
Bonus Prediction #2. The Reappearance of Dark Sister
There is a Valyrian steel sword which Arya mentions in an earlier season while talking to Tywin. The sword she mentions is "Dark Sister", a Valyrian steel sword which had once belonged to a Targaryen woman. The sword was small and slimmer - like Needle is - and designed for the hand of a woman.
It is possible that Arya could end up with the sword Dark Sister instead of Gendry forging her a new sword, or it is possible Dany could end up with the sword instead, as it makes sense that at some point Dany should start wearing armour and learning how to defend herself. She won't always have her dragons handy so she really should have a sword to defend herself with.
Either way, someone will end up getting Dark Sister and Arya and Dany are the two most likely candidates.
Bonus Prediction #3. When Arya heads north, she will reunite with her dire wolf Nymeria
And Nymeria will be big enough that Arya can now ride on her wolf.
But first she needs to head south to King's Landing.
Bonus Prediction #4. Cyrio is not dead and neither is King Stannis
Cyrio is alive. Somewhere. Stannis is alive too, but now missing a leg.
My prediction is Cyrio will pop up in the north east, roughly west of Braavos.
I predict Stannis will pop up during a plot twist involving Brienne, in which she explains that she realized Stannis was the rightful king, that he was only doing his duty as king, yada yada, and that she realized she needed to punish him but not kill him.
Bonus Prediction #5. Podrick Payne is one of King Robert's bastards
While everyone knows Gendry is one of King Robert's bastards, I have a hunch Podrick Payne is also one of King Robert's offspring.
The revelation probably won't be revealed until after Gendry and Podrick meet, and they will only learn they are half-brothers thanks to Bran.
This will become important because it will mean that they are the rightful heirs of the Baratheon family, which is why keeping Stannis alive for now becomes important.
It also should be noted that the Baratheon family are relatives of the Targaryens. So both Gendry and Podrick do have a bit of Targaryen blood in them.
