Let's build another setting! (Flare Tower)

[JoshuaZ]

This setting would not have humans in it by original design, they can't climb very well, and similarly having some vertical movement abilities are kind of important.

Huh; I hadn't gotten that feeling at all. My immediate thought when I saw it was that the sides of the tower were going to end up having all sorts of stairs and maybe some just on the inside in the easily accessible parts.

Edit: Keeping with your idea though:

8) The most common sentient species are the Asperansi and the Lenalas. The Asperansi are cat-like beings with a prehensile tail that can actually hold their entire weight. Combined with powerful claws they make excellent climbers. The Lenalas are gremlin-like generally with small but powerful wings. However, their wings grow over time even after they have reached maturity; this growth rate is slow and it slows down over time but never fully stops. An elder Lenala can have a wingspan as much as 10 feet. While the young Lenalas can only use their wings to glide and control their fall downwards, the more mature ones can actually fly.
