You live in a world called the false earth, it is a “sister dimension” to earth which means it retains so close to earth on its timeline you can travel between them it only certain people in the false earth can travel between the dimensions at will, rulers cannot die from natural causes until they step down, or they can be killed, the false earth has had years of prosperity under queens arya and eworin, but, seemingly out of no where, an unknown force came storming to the palace, an army of only 100 stormed it, with power never seen before and killed both queens, the new ruler established himself as king calix, and took hold, separating families and forcing people into his army, many are never seen again, he broke off the world into diffrent kingdoms, many much poorer then the main one, Samar, you currently live in fyn, a frozen tundra, on the outskirts of the world, and you see this person passed out in the snow, you recognize him as the queens son, atreyu, but noticeably much younger, 11 at most
