My idea for Saguans is that they were throughout most of Dar nations, including a lot of Himalia, Sagua, Height Sagua, and Key to Don, that region north of Blaland, Hellpotatoe also adopted them before he left, which is east of Blaland, and northern Darvincia also has a lot of Saguans (the Nausikaa region), which is why I thought it was silly that you wanted Blaland to have no Saguans yet you were accepting of other races/cultures.
Saguans are a cat-like species, except they are humanoids, and they can have a variety of fur patterns depending on where they live. My idea was that they evolved long past from a tiger-like species which became smaller and more intelligent along one path, with Saguans splitting from one of those species and their "cousins" becoming a small feline that hopped through trees and could go on all fours or on two legs, and stood about three feet tall and had basic tool usage.
Saguan hands will be naked on the bottom (the palm side) and full fledged fur on the top of them (the knuckle side), with fat pads on the bottom that have little or no nerves in them like the bottom of human feet, they will have 5 fingers (because skeleton is much harder to evolve) with 2 joints, and one joint in the hand that is "hidden" thereby making the fingers shorter, the fingernail is also replaced with a retractable claw in order (at least in the past) to open up small things like nuts and to tear flesh since in the past they were carnivores and not omnivores.
