Hey! I'm working on a setting too, and there's something I'm getting stuck on. In her Songbirds style guide, snow mentions some suggested elements that make up a Songbirds setting. One of these is to have 10 Classes (for worldbuilding purposes), but try as I might, I cannot find what "Class" might refer to in the corebook. There's a mention of "class abilities" in a table somewhere, but no section detailing specific Classes or a description of what that term means in Songbirds.
Notably, Freelancers are distinct from Classes, since the style guide also mentions that you should have 10 Freelancers for a setting.
I wish I could afford Chevalier to reference right now lol. How are you interpreting that "10 Classes" suggestion? My current best guess is like, roles which songbirds can step into, specific the setting I'm building. I've got some stuff written out narratively -- ex: a class for pseudoscientific reverse-necromancy, a class for 'that guy everyone knows,' a class called 'The Vestigial Worker' -- but I have no idea how to approach making mechanics for each of these. Should I? Should they each have pre-chosen Skill proficiencies? Gifts and Curses? And what is this about "class abilities?"
Maybe the answer is 'whatever you want,' and I'm overthinking this.
