I don't like it. I feel like the story is just destrying the most interesting aspect of GOT, which is that there is no real bad or good, like everyone is just an egoist. The one who win in the end or not even necessarily the better one of the group. Here, in this story it just end up in a manichean conflict between "good" vs "bad", it's boring.
Also, i feel like there are plot hole in the way MC use the force, like bro, if you want revenge why go to essos, you only need to go to all the weak minded noble and manipulate them. Like there could be so many way which i feel would be easier.
It's not a really good GOT fanfic. It just denaturate GOT.
