The Main Character is a Male Targaryen who is named Eragon Targaryen, he is Daenerys Targaryen's twin brother.
This is tagged Yuri because girls in his harem will get intimate during sex with the MC and people cry when they aren't warned. (people also seem to cry when they don't instantly see Yuri sex if it's tagged Yuri, you can't make people happy.)
This is AU - This is an Alternate Universe of George's world.
Expect people and things to be entirely different because of small changes butterflying out. Alternate Universe! Like how
The entire first 25 chapters is a 'Time skip' until Eragon is 14 years old. So the first 25 chapters are just random POVs of others and him to build up the world and show changes. Instead of just saying "he was born and 14 years passed." I wrote out the 14 years in a 'fast' way and showed some character build-up for different people.
Now that the easily triggered have been warned I can let you know more about the story.
World exploration and conquest will be a big theme in this over the many chapters it will eventually be. So far he hasn't gotten around all that much but it's only chapter 70 out of like at least 1000 if I estimate it right. And that might be shorting it quite a bit as I will be making this a very long fan fic.
Dragons are in this, new ones.
Magic will be touched quite a bit, nothing like altering reality but definitely a cool flaming sword.
I like to think I build up the characters pretty well and have them stick to their personalities pretty well.
I said it before but world exploration and diving into the lore of new places are one of the things I look forward to the most so it's a pretty big part.
I don't know what else, try it if the world of ASOIAF interest you, if it doesn't then this wont be something you like in the slightest.
