...finally got around to reading this.... hahha sorry it took forever!
I love the world you are creating and feel excited to learn more about it,especially about how it got that way. The hidden history aspect is extremely similar but it seems the way the world looks in our stories is entirely different so those hidden histories will likely be very different stories as well. How far along are you? I just wrote 3 chapters before steemit came along, I was still focused on my collection of short stories which is 70% finished and which I should get back to.
And as far as whether it’s “good” or not, I’d use your own satisfactions with it as your main guide. If you love it, the right people will love it too!
