Well that's rather deeply depressing.
It was from me reading Magnara(ASOIAF/Girl Genius)where Tormund explained why it would be a VERY bad idea to go south
(
"I trusted you," Agatha said, not looking up.
"Where did I do you wrong, girl?" Tormund said, puzzled.
"When you didn't tell me what this Night's Watch did when it heard about smiths among the free folk," Agatha said. Tap-tap-tap. "That they do their best to hunt down anyone with the skills to work iron and steel."
"That? I didn't think it worth the bother to mention," Tormund replied. "If the crows ever tried, you'd paint the forest red with their guts."
"I don't want to get into a fight with them!" Agatha snapped. "That's your plan, isn't it? Have me start teaching your people smithwork. Then when the Watch finds out, I have such a big target on my back I can't go south."
"Har! That'd have been a cunning plan if I'd thought of it!" Tormund said. "No, I just thought you'd end up back here after the first time a southron lord tried to make you bend the knee. 'S why me 'n Osha plan to head south with you when summer comes. I want to see the fur fly!"
"I don't know whether to feel betrayed or depressed," Agatha said. "Tormund, I can actually co-exist with these lords. Just because I don't intend to bend the knee means I'll be fighting them for the rest of my life."
"And when some lord whose lands you settled on orders you to make your wonders for one o' his wars?"
Agatha's lips tightened.
"And if he threatens you and yours if you don't?" Tormund continued. "Or says you've to marry one of his sons, so that his line will carry down your Spark?"
CRACK as the dragonglass split down the middle.
"Aye," Tormund said, the cold winds howling outside. "You said it yourself. Maybe you'd be a Heterodyne of old. And that's what the lords south who stole from us all we had and drove us beyond-the-Wall deserve.")
It would essentially result in something similar to what happened to Ymir in Shingeki No Kyojin
Enslaved and taken advantage of by some primitive warlord who may not even be that powerful or prestigious compared to his neighbors, used as a weapon and a way to make things like transportation and trade easier, made into an eventual object of hatred by others and with a broken will
With Great Power Comes Great Responsibility
