I am making a fantasy story where a guy who starts from the bottom eventually becomes top-dog of the entire area through his own efforts.
Let's say a charming and highly intelligent modern person (a genius) gets dropped in a medieval fantasy world.
Besides humans, monsters also exist in this world, but they are brutish and will kill any and all outsiders. The man in question has good intentions, but he'll play dirty if he must (kind of like a Machiavellian guy or Lex Luthor from comics).
