[ASOIAF/GOT/DC] Song of Hero and magic

Reincarnation isn’t so bad, I must admit. I never expected to be so lucky as to be reborn as an adventurer in a fantasy world, especially one that also has superheroes like Superman, Batman, and Wonder Woman Through my determination, I climbed my way up to become a king. Yet, there is one thing that puzzles me—Why does my kingdom have a portal to the Game of Thrones world and why is the world I know surrounded by invisible walls? Disclaimer: I do not own Game of Thrones or Asoiaf and Hero and villain of DC or Dark knight of steel Disclaimer II: Some stories will feature topics such as torture, rape, sexism and xenophobia. These topics do not represent me, I only seek to give the most historical perspective possible to the social relations of a medieval era when they meet a Hero medieval fantasy world And that includes the atrocities of villains and anti-heroes. . Disclaimer III:I don't speak English, I am in the process of learning, so I will make several grammatical mistakes, any help on the lexicon is accepted, I am not a person so deeply versed in the lore of GOT or DC
