I want to do a funnel running 15 characters at once but it's hard. Trying to make all those people and sort of imagining some plotline.

I want to do a funnel running 15 characters at once but it's hard. Trying to make all those people and sort of imagining some plotline.

So even though the funnel I've selected is faux medieval Europe, I've decided to put it on an alien planet with retro future, seventies sci fi colonists instead of filthy peasants.
But that didn't make it much easier. I was looking at costumes and hairstyles and I'll need a list of names and personalities... Anyone else find solutions?
I could use Maze Rats and churn out a horde of characters and there is a purple sorcerer tumbler.
