What is your character's species?
The choice of species and career can go hand-in-hand and stress a character's background story above all else. Any species could ultimately fit any backstory. There are more species than this, but these are the species I have information and stats for.
If you want to play a species that is not listed here, let me know and I can work with you.
Don't worry too much about the stats, since they can be altered with starting XP. Instead, find the species that fits your vision or backstory.
