one word, or maybe two actually, depends on what rules you use: worldbuildingWell, that's exactly what I'm trying to understand. There would not be a 20 characters if he didn't thought he needed them, kinda obvious.
What I'm asking is why 20? I understand the challenge of writing and giving depth to 1 character, let alone 20, hence my questions. When I saw all of their faces on a banner I was like "That might be too much to handle, 20 characters in no joke, some of them might be fillers".
So, is this like a rollercoaster or a deep dive? Still tryin' to understand.
