Concept: an RPG setting where the ruling class consists of talking spiders with a penchant for fancy hats. Not anthropomorphic spiders - just regular-looking spiders, about the size of a largeish dog, that are sapient and capable of speech. The setting isn’t a horrifying arachnid dystopia or anything; it’s actually a fairly conventional high fantasy milieu, except that all the royals, most of the hereditary nobility, and a fair chunk of the gentry are spiders, with all the cultural strangeness that implies.
(Stairs are considered lower class - the spiders climb, of course - so wealthy humans build multi-level dwellings with no stairs and develop their free-climbing skills in order to imitate their eight-legged neighbours. The spiders, for their part, pointedly ignore the handholds cunningly disguised as decorative moulding, because it’s rude to draw attention to a person’s disability.)
