Hey, I can't believe I'd ever write this, but
I know that probably no one will answer this, but I will treat it as a conversation with myself xD
I'm thinking about creating my own world in which some of my old and new commissions will be happening
and maybe I would slowly create such a world and who knows, maybe one day I will make a story xD

As for the world's premise, I'd call it Brave a New World.
The premise is that this is our world, but instead of humans, there are anthros. In the 1950s, a catastrophe occurred where 20-30% of the world's population shrank to a very small size. The current time is 2020-25, where the world has normalized and acclimated to the new world. So far, no one has found a solution to this problem, and over the years, only few recognize the new micros as equal beings; it's even normal to consider them worms. And rumors are circulating about technology that can shrink ordinary anthros.

Most of the micros themselves have regressed to tribal/medieval development, with some exceptions, especially when new generations emerged who didn't know normal life, and the world has always been this way with all this walking monsters or gods.
And I'd present various situations, short stories, etc. I won't deny that I was somewhat inspired by Todd, so check out his world.
