Hey, I was wondering if I could get some help brainstorming the fourth new race of my story, because I know I want there to be five races including humans and I want to know for certain what all of them are so I can plan ahead a general outline for what the world will look like after a few decades, but I'm drawing blanks as to what I want the fourth nonhuman race to be. The way the races work in my story is similar to Shadowrun, in that all of these people used to be human before the supernatural shenanigans around modern day (2012 to be precise in Shadowrun) caused these new races to appear. However, while these changes were forced upon the characters of Shadowrun, here they are voluntary. Forgive me, there's something of a wall of text incoming, because the way races work in this story is a little weird and roundabout. This is an urban fantasy story about our modern world after a mysterious entity starts to, week by week, give humanity supernatural powers marked on a brand covering their inner forearm. It's a story of how we adjust to this, the numerous social, economic and political problems it causes, and four college students and their effort to adapt to a world that's rapidly becoming nothing like they thought they were going to have to deal with when they grew up. Every week, everyone on earth over the age of 13 (the age the brand appears) has a new symbol representing a new power added to the brand. There are six "circles" for powers on the brand, the powers in each circle can be moved around if you focus your mind on it while looking at the brand, and when they hit six the new power replaces whichever power was in the top circle. There are also four powers that were handed out to everyone who was over 13 in the first month after this started, and these four cannot be removed. Okay, so, basically the way races work in this world is that early on, some powers start "dropping" that grant people the ability to shift to a completely genetically randomized body that's a member of one of these new races. The idea is that for various reasons, a lot of people decide they prefer these new bodies over their old human ones and decide to adopt these bodies full time by discarding the power, which turns out to not turn them back but lock them in whatever form they were in when they gave it up, thereby letting them keep the body they prefer without losing a brand circle. The first race are the Peritails, who are basically my story's elf counterpart in that they're the most human-like aside from some minor features, specifically antennae for ears, long slender tails ending in a hand with a centered opposable thumb, and skin and hair colors ranging on the spectrum between red and blue and the purples in-between. Most of the people who choose to become this race fully are people who for whatever reason lost the human genetic lottery but won the Peritail one. People who find they were given way more attractive or otherwise viable Peritail bodies than human ones. Most noteworthy is the fact that, for completely unknown reasons, every transgender person on Earth, and no one else, was given a body that was the opposite of their biological sex rather than matching it, meaning that transgender people now have a real, natural, can-have-children body whose sex they actually identify as. While the theories on why the entity(s) responsible for the powers did this range from the benevolent to the cynical, what's important is the result, because I really want to throw these people a bone. You see, I soon realized to my horror that the healing factor power I need for the story would have horrifying side-effects on the transgender community that I simply can't avoid if I want the power to work the way I want it to. But anyway, basically these are the people who pioneer the concept of going full transhuman because why on Earth, in this dangerous time, would they waste a "power slot" to keep access to a body they don't even like? Next come the Wraiths, a race whose appeal lies in sheer utility. As I explained in my other thread (TL;DR, one of the powers creates a situation where most of modern technology can be made to work but vehicles are very limited and easily sabotaged just by looking at them), speedy transportation becomes important, and these guys are basically kinda like centaurs except they're sleek and jet black all over and instead of having a horse's lower half they have a giant chitinous insect abdomen capable of levitating a foot or so off the ground and propelling itself around at high speeds that are almost comparable to cars (though with low traction). Due to their bizarre and creepy appearance a lot of people are reluctant to become these things full time, but some people make the sacrifice of turning into them full time if their livelihood depends on the extra power space, or if they're soldiers who want to make use of the race's significant combat utility (imagine, in a world without guns or tanks, horseback archery with a completely smooth ride. That's what they can do, among countless other things). And then there are those who embrace the creepy, intimidating appearance of it and become them full time for the sake of it. Third, the last one I have a solid idea of, are the Greys, which are basically vampires with all of the weird kryptonites and supernatural powers taken out of the picture. A lot of people put two and two together and realize that their seeming undeath, translating to a lack of a need to breathe or even keep their bodies warm or cool, combined with some inherent pressure resistance, means that these "vampires" are actually perfectly at home in the ocean (where the sunlight can't even reach or burn them), resulting in a lot of people suddenly getting the idea to take these forms and try and colonize the vast unclaimed territory of the ocean and build their own sovereign states there, attracting a lot of people who want to try out bizarre, obscure or previously-failed political systems. Unfortunately, a lot of these societies don't work and their breakdown over the following decade or two results in the seas being full of what are basically amphibious vampire pirates, which complicates sea travel immensely once they start using ships again. As for the fourth one, well the only real idea I have is that the idea of a flying race appeals to me, but... ...What you may have noticed is that what I'm trying to do with this is give these races, with the partial exception of the Peritails, a sort of artificial built-in culture by having the fact that they're voluntary cause their traits and specialties to attract and discourage specific types of people, so that even after a timeskip in a later book to after the first generation of naturally-born members of these races reaches adulthood, they'll already have their own distinct cultures, trends and stereotypes in a lot of places almost as if they had been around for centuries. And I have this feeling that if I give the last one such a universal appeal as flight then I wouldn't be able to do that with them. I can't think of a good combination of traits or weaknesses to accompany wings that would attract a distinct and interesting group of people. So if you're still with me, first off, thank you, and secondly, here's where you come in: can you help me think of any features or traits I could combine with wings to give the "first adopters" of this race a distinct culture to them that would make for interesting stories? Or if you have any random thoughts for other ways I could go with this race, or even any input on the first three as I described them, I'm all ears.
