There's definitely a steel city mystery vibe to my gym.
A bit of steampunk, a bit of noir about it.
Trainers will give clues on how to get through the back alleys.
If someone gets lost, they can re-fight a trainer to get an easier clue. (Or more exp, I don't judge)
Also, one trainer is a Nurse, who will heal you.
My badge is the Detective Badge, and I give the Flash Cannon TM.
this sounds amazing holy moley
