What is the best way to travel from the far north to the south?
The first option is by sea. Using ships, they could bypass the northern lands entirely without having to deal with them at all.
Haldor believed that would be the best option, as it would avoid bloodshed. However, being the grandson of the king in the north, he should try to negotiate with them and find a way to enter through the north.
The reason is simple: not only would they better leverage their options in case of war, but it would also leave the enemy in the dark. They wouldn't know the exact numbers of their army, and in the event of war, they would have two key points to attack.
Everyone knew how Aegon the Conqueror took control of the Seven Kingdoms, and if a grandson of the Starks had a dragon, it might be easy to ignite the flame of rebellion.
It's not as if he was asking for the forces of the Starks; he was simply ordering in plain words that they open the gate of the Wall so that the armored bears and, if possible, part of the far north army could secretly enter the north behind the Wall.
Haldor wasn't sure he could get the forces of the wildlings beyond the Wall and was also somewhat reluctant to the idea of allying with them.
Control could be minimal in his plans; if he brought them south, he shouldn't make hasty mistakes.
The Wall was large; those in the north didn't have the power to protect it completely, especially from the forces of a dragon. They should think twice about their options and realize that even if they asked for help from the southern dragons, it would take a long time for them to reach the north.
By the time the dragons arrived, they would have complete control of the Wall and the nearby cities.
The armored bears would set up defenses, and the sky would be filled with fireworks that would destroy any dragons trying to reach their camp.
But Haldor wasn't a fool; he shouldn't step on the wolf's tail, or it would bite him.
Everything had to be done calmly. Haldor knew everyone would avoid a war when they learned of the existence of the White Walkers. Even so, that wouldn't stop them from taking control of what belonged to them.
Rooaarrr!!!
Boom!
Haldor could see the tower below him. They couldn't fly too high because of the cold winds, but it was safe to rise high enough to pass over the wall.
As a precaution, they entered an area with few guards, giving them the chance not to be attacked.
"Holy Mother of God..." The guard on duty didn't know which signal to send, but as it was urgent, he sent the most complex one, which was that they were being invaded.
Boom! Boom! Boom!
The bells rang loud and clear, but not quickly enough for the soldiers below to prepare.
Before they knew it, a dragon had descended from the sky and landed on the ground near the houses where the other soldiers were.
"Ahhh!"
"Everyone aims at the dragon."
"Don't be idiots; don't shoot."
Roaaarrr!!!
The commander of the night's watch trembled at the sight of this dragon. He knew it didn't come from the south because he had never seen a dragon like this, which was practically made of ice.
"No one moves."
"That's the best decision you can make." At the best moment to appear, Haldor looked at everyone as his dragon Azazel bowed.
"Those emblems…" Tormada, the Commander of the Night's Watch and also a Stark, recognized some of the emblems displayed on Haldor's armor.
Haldor hadn't expected this, but he said anyway, "I have a letter for the Lord of the North. It must be answered in a month when my people arrive at the gates of this wall, and only then will I know what he thinks."
"Who are you?"
"That's not the question you should be asking. Remember well, if my letter is not answered, then you will be treated the same way as our enemies in the south." Haldor didn't want to say more. As soon as he left those words in the air, he mounted his dragon and soon disappeared into the sky.
Tormada remained silent, still trembling, looking at the letter a stranger had asked him to deliver to the Lord of the North.
"What do we do? That was a damn dragon; I thought only the Targaryens and Velaryons had dragons."
"We must deliver this letter to our Lord. The North is in danger."
