The game is very liberal with level and place in the world, even by 5E standards. I mean, Hells [literally], storywise this is not a low level campaign. All of the origin stories, including that of blank Tav, are way too epic for level one characters. If I were to come up with Wyll or Gale at the table, the DM would go; "Whoah, there cowboy. Tone it down a bit."
