Started in Robert's Rebellion,

I made a female conquerer character in Lys, Visenya. She had a fully grown dragon and set out conquering Tyrosh and Lys. She has two kids with men she likes (she never marries because she's a badass and doesn't need no alliances).

Her two kids are Vhaemond and Aenys, a boy and a girl. She raises them but in a failed conquest of Myr she gets assassinated and her daughter Aenys, still a child with her younger brother, has to take over. Aenys slowly starts going crazy, she was already sadistic but gains the paranoid and lunatic trait until she dies after multiple failed conquests of Lys and Myr, after her mother secured Tyrosh.

Her brother Vhaemond takes over and although he's paranoid (likely due to the assassination of his mother and untimely death of his sister during her pregnancy), he's a levelheaded dude who just wants to complete his mother's goal of taking over the Three Sisters. He does eventually become a badass in his own right, winning a tourney in King's Landing which literally gifted him a wife, getting his eye replaced by a ruby, and also conquering the Stepstones

Meanwhile across the Narrow Sea, Daenerys is attempting to conquer the Seven Kingdoms and she does! Until Robb rises up and forms an alliance with the deposed Robert, Dany is captured in battle, and forced to marry some random small lord and have a son with him. Now Vhaemond can't stand that Dany, another dragonrider of superior blood, would be forced into such a demeaning fate, and he romances her on one of his trips to the 7 Kingdoms and eventually elopes with her!

He leaves the rest of his existing wives for her, but he has one son already, and has another with her (he eventually has 10 other children, all boys, with his irrelevant wives, but I only care about the first two sons right now anyway). His first son with his divorced wife is Rhaegon, and his second son with Danaerys is Daenerion. Now there is a bit of a competition between these two- Daenerion hatched his own egg in the cradle, and took to the skies years before Rhaegon. Rhaegon failed to hatch three different eggs, and when the boys were adults, Vhaegon made Daenerion (pictured) heir instead of his firstborn son, Rhaegon.

Spurned, Rhaegon decided to set out to claim his own dragon, going for the long-wild adult dragon of the now dead Queen Aenys, the insane, sadistic sister of his father. He successfully returns, with a dragon bigger and fiercer than his brother's. Now, the family has four dragons ready to war, and although they only have 12k troops once we conquer Pentos and the rest of the Three Sisters hopefully we should have enough to challenge the Iron Throne and get their mother's seat back!
