Game of Thrones: the king of conquest

A young man who sees no interest in today's world and who is inspired by movies, series, novels, manga and anime, dreams of going into these worlds and fulfilling his desires, but one day on his pc he takes out his ticket to his desire, that of domination. Ps: I am a fan of the nasuverse so I could refer to it. Game of Thrones does not belong to me but to George R.R. Martin.
