Personal Fanfic Ideas

This story is about (isekai/or not up to you) the a bastard of winterfell (can be Jon as rhagear's son/ Jon as ned's son/ or an oc as Brandon's son) in a mixed world (ages are got canon, meaning robb would be 18 not 14 for example. But would have more characters like Willas tyrell). The story starts 4 years before Jon arryn dies, where the mc gets op magic, but doesn't really care about westoros and wants to be a king. At 14 leaves the north, spends the next 2.5 years cleaning valyria of its foul magic, rescues needed citizens, builds his new government/military force, and establishes new kingdom simply called The Freehold, as a nod to the greate empire of old. Then finally 1.5 before canon reveals his new kingdom to the world and shit hits the fan from there. His house name and words are: House Frostbourne - Wolves of Freedom (can be changed ofc) while the banner is a silver wolf with a crown of laurel leaves, surrounded by a circle of flames, symbolizing victory and liberation.
