This is less a story than a possible history for the Vulpinevan universe. This is the post-apocalyptic history. Personally, I prefer the "It's just an alternate universe where animals evolved differently. I'm a fantasy writer, so I don't need to explain more than that" explanation. However, if you are more scifi oriented, you might find this more satisfying. Personally, I dislike the idea that the nonhuman animals' society evolved from the remnants of human society even if it probably makes more sense for an explanation of the similarities just because it gives humans too much importance in the universe. I prefer the idea that humans were just another species, and a shitty one at that, and similar technologies and stories exist just because some animal person came up with those ideas on their own.
