I loved the world building in this story, and I would love to see more stories set in this world– the concept of the gods creating civilization/order, and the chaos outside of that, was really cool and seemed like it could lead to a lot of great stories.
And as an autistic person myself, I liked the portrayal of Rob, for the most part (I am pretty sure he is meant to be autistic, although he may also have ADHD or both... I'm not sure his exact diagnosis really matters, though, especially in a fantasy story where none of those diagnoses even exist in the first place). It hit a bit close to home to see other characters, including the narrator, constantly refer to him as a burden and unable to be a productive member of society. I was glad that Rob's detractors were eventually proven wrong, though!
His storyline did hew pretty closely to the trope of the magical disabled person, where his disabilities were negated by his supernatural powers, but I appreciated how well-explained his magical-seeming abilities were within the story. It wasn't that his disability made him magical; it was that his inattention was, for once, an advantage, making him unaffected by the Chaos. So it was a particularly well-done example of the magical non-neurotypical person, and although he's a savant of sorts, he also was a well-drawn three-dimensional character. In general, I'd like to see non-neurotypical characters that don't fit these stereotypes and tropes, but I think it's also important to have interesting and fleshed-out characters that do fit these stereotypes, and this was a good example of that.
Minor issues with disability stereotypes aside, this was a beautiful story, in a fascinating world, and with characters I really liked. The descriptions of the Chaos were also really well-done and creative. And I, too, hope for Rob to become the God of Chaos!
