In the trailers for Season 7 of Game of Thrones, we get to see Jon Snow with a group of companions traveling North of the Wall. It has been rumored that they will try to capture a wight and bring it back as proof to the Seven Kingdoms that the White Walker threat is real. We know that Jon will be accompanied by Sandor Clegane, Tormund Giantsbane, Thoros of Myr, and Beric Dondarrion. Some of us speculate that Jon may also be joined by Theon Greyjoy, Gendry, Eddison Tollett, and members of the Night’s Watch, wildlings, and the Brotherhood Without Banners. I have a feeling that Jon and his group of companions may be a homage to Old Nan’s story of the Long Night and the Last Hero from the books.
In order to understand the full details of Old Nan’s tale, you need to know the full story. Old Nan talks about the Long Night, which was a dark winter that lasted a generation where kings froze to death in their castles like the shepherds in their huts. In that darkness, the White Walkers came for the first time. They were cold things, dead things, that hated fire, iron, the touch of the sun, and every creature with hot blood in its veins.
When the Long Night was at the height of its terror, a Last Hero sought help from the Children of the Forest. He was accompanied by twelve companions, a horse, and a dog. Over time, the Last Hero lost all of his companions, his horse, his dog, and his sword froze so hard that the blade snapped when he tried to use it. While traveling alone, the Last Hero could feel the White Walkers hunting him with packs of pale spiders that were as big as hounds. What happened after that is unknown.
I strongly suspect that Jon Snow and his suicide squad are the next incarnation of the Last Hero and his twelve companions. If that is the case, there is a very strong possibility that not all of them will make it back to the Wall alive. It will also allow us to see more hints if Jon Snow really is the Prince That Was Promised and Azhor Ahai reincarnated. Only time will tell when Jon Snow faces the Night King and his minions for the first time since Hardhome. I also hope Thoros of Myr gives them one of his prayers before setting off beyond the Wall. For the night is dark and full of terrors and only the Lord of Light himself can save them from the Great Other!
