The story takes place in a just recovering Earth! It's in that awkward pre-teen phase of 'we just got destroyed' and 'we're all good bro'. Spiderish lives in one of the more completed towns, though it's still pretty rural. It's not exactly a rich people area so it's going to stay more or less that way

Some animals have warped so that most of them have a form of camouflaging that makes them appear like native fauna and vegetation. For example, rats look a lot like radishes (so they're 'ratishes' :D)

Animals that are exactly as what they were before The Accident are very valuable and incredibly expensive to maintain. In fact, it's very illegal to hunt them and, in most cases, to own them

Sea animals are incredibly dangerous. Some areas have figured out which ones are safe for consumption and where to fish to avoid trouble, but for the most part it's really a game of lottery to see if you come back alive. Most beaches are illegal to enter because of it

Warped humans typically only warp much like animals do. Multiple or lacking limbs, pigment mutations, irregular size, etc, etc. It was considered impossible, until recently, to have mutations that resemble animals or anything like that

People are usually born with what they're going to have, as far as warped features go. There is a new 'dormant' warped gene theory coming out for people who've spontaneously warped, but it's still too new for anyone to say for certain if it's even real or not
