I was thinking of running a campaign of Blades in the Dark in New Capenna. It's a setting from Magic: the Gathering which is a 1920's style crime city, last city in postapocalyptic wasteland of what was once a typical fantasy world.
There is one problem. New Capenna has fantastic races/species/ancestries, whoever you wanna call it. There are humans, demons, cap people, bird people, rhino people. I know Blades is by default a game in a setting only with humans. Are there any ways to reflect mechnically choice of different species by a player? Any guide hwo to decide which abilities wouldn't break game balance? Or should I just lift ancestries from one of other Forged in the Dark games, like Band of Blades or Scumm and Villainy, and change names?
