I love where this could go... so many possibilities ! If writing a whole book seems daunting, just do a bunch of short stories when an idea comes into your head. Some can be linked, others just set in the same world. Over time, the depth, detail and richness will grow, and you'll find that there are some characters you introduce that really work well for you. Then, those short stories can either become an anthology, or at least provide detail for if you decide to write a book.
You need to do it, because I want to read more from this setting ! 😁
