A few things.  First, you can find my earlier posts on this Science Fiction 5e thread here, and here. Second, let me know if you like these.  I will keep writing them if people are getting anything out of them. Third, sorry it took a day or two longer to get this out.  Writing races is not as exciting and writing classes. I also had some other issues going on, but real life is like that some times. I did briefly consider doing my own artwork for these, but remembered I am not a great artist.
