A ‘fall of autumn’ is a period of change, where a person/other/group has risked something, or let go of something, in order to change- despite not knowing if it will be for the better or not.
Autumn literally means change, and a fall of autumn is taking the chance to change.
“This is our motherfuckin’ fall. Our motherfuckin’ autumn. And you know damn well we ain’t gonna let nobody take it from us!!”

“Everything we’ve strived for leads to this autumn, and to this fall.”
“The fall isn’t supposed to hurt. It’s the autumn that really gets ya.”
“At long last, our fallen autumn has arrived..”
“Back before everything- before the fall- autumn didn’t truly exist.”
“Well, how was your fall of autumn?”
