at least for me, these are the big things I'd want to know before I consider apping to the game.
- more information on cursed vs. unswayed and why you'd pick one side or another. for example, what does the curse word DO?
- explanation of flavor text and world specific items! what's meeting of the Moon? what exactly is a Kinu?
- what all can characters do in a day to day situation?
- it's fantasy based, but what's the level of fantasy? are we talking more Diana Wynne Jones or Game of Thrones? fantasy is such a huge genre, that you'll want to use precise examples and definitions otherwise someone's going to shove a car in the middle of the Shire.
- hints of the ongoing plot. you say that the characters are brought to make decisions for the three cities. so will this be faction based? politics based? basically, what's to stop characters from digging in their heels and not doing anything.

also, here's some questions that you'll inevitably get and might want to go ahead and edit in:
- 'characters don't come in with any item': my person needs their asthma inhaler/soul gem/fancy magical headset to survive, what about that?
- 'some powers are nerfed': my character eats souls/drinks blood/feeds off ambient magic, what about that?
- questions about the devices: are they tech, are they magic, can they be hacked, etc.
- what about CRAUs, apping two characters from the same canon, or apping duplicates of the same character.
