Who will sit on the Iron Throne?
Jon Snow of course. But here's how.
1. The White Walkers will breach the wall. The war will commence when the White Walker King sounds his horn. And then the wall will fall.
Jon Snow and his army will fight the White Walkers but will not be able to hold them off. They will retreat south to receive help from his aunt.
Once they are south he will link up with Khaleesi.
Khaleesi will invade King's Landing. She will be victorious.
Cersi will not take too kind to this attack. She will try to roll out the wild fire but will be killed by her brother the King Slayer who is now the Queen Slayer!
During the course of fighting Khaleesi will die a hero and Jon Snow will take the throne. A Song of Fire and Ice is about Jon Snow. He is both fire and ice from his parents Rhaegar is Fire and Lyanna is Ice so the whole title of George Maarten's books is about Jon Snow.
Jon Snow 4 Life!
