Well, the North had several immense mountain ranges. The first and most notable was the monstrous mountain range of the North that was very close with the New Gift and Brandon's gift that was under the control of the mountain clans. These mountains had gold, copper and iron. The largest amount was iron followed very closely by the other two elements as is well known to be found in nature.
The following incredibly valuable and remarkable mountain range was of course and fortunately within the lands of the Starks which was a more than solid advantage since it meant zero problems for him with respect to the above. This chain was south of Winterfell and was surrounded by the white knife which was excellent. This one was overflowing with gold and was excellent as a position so obviously it would have to be exploited.
Nothing and no one would tell him in the least not to touch the place because it was technically from the Stark house. Did anyone have a problem? I could deal with these people in a very good way with a firm reminder of who is in charge.
The following two chains are those belonging to the Cerwyn house and the Hornwood house which brought him a more than important grimace in truth. Cerwyn was an important ally of the Starks part of the Winter alliance an alliance created by those who were basically at antanimous the Boltons for their tactics and methods. They didn't like the Boltons.
Hornwood had been a neutral house but through a lot of work he had discovered that the Hornwoods had allied themselves with the Boltons since in their own words they were tired of dealing obviously with the Stark family not recognizing their own words of course but in the hands of ignorant they can mean anything anyway.
The Cerwyn House had important reserves of silver and precious jewels, which was excellent. Unfortunately Hornwood had iron and gold along with a little copper. It's not to mention that it was bad.
He was a Black and had wisely learned the lesson that it was better to have your enemies in two ways: dead or weak. He honestly prefers them dead. They are minor headaches, which is usually always an event that you have on you since there are many people who are always upset with a person when he is powerful.
A dead enemy means zero problems and zero difficulties at least in Hariric's mind of course and that was important to him since he wanted to have a good time with his fucking family.
The last decent-sized mine (i.e. Lannister size) were the Skagos mines. Harris seriously wanted to hit his head. Skagos was a carcinogenic point in his mind. He was not one of those to advocate for the death of an entire group but on the one hand those of Skagos would never accept the Northerners because they were xenophobes and then because they were one of those who had accumulated bad blood with almost all the houses which was incredible if he himself had to say it.
Add to that that that the island, although without trees, was an ideal place to become a shipyard in the same way that Bear Island was and you had weighty reasons to hit them to shit but of course some would say that it was morally bad to do such a thing anyway (not for him since he was Black).
The more he had looked at the North, the more he realized the importance and value of doing something. It was time. They had had eight thousand years to be lazy lazy without exploiting their country to fuck for his soul that he would not tolerate it anymore.
Besides, he wasn't going to tolerate his nation being full of uneducated fools. While it is true that people could come up with ridiculous ideas such as democracy (Democracy on paper is fine but for it to work the people must be educated. Since when are rulers interested in a cultured people?) But a cultured people means several things such as good building, good military work and doctors. All that was of great value.
Raming himself with courage (hey, his father was terrifying half a meter eighty and he was pure muscle while the idiots of the south were worthless lanky in reality) he opened the door.
He loved his family above all but it would not be difficult for him to admit that he had a lot of respect for them. One does not become a lord of the North for being a kind man and woman ruled out of respect and fear. Nothing and no one had more value in their bodies than both of them so I knew that their questions would possibly be enough to cause a certain discomfort but this had to be done for the good of the North if they wanted to shine as a nation.
