The galaxy is a vibrant place of many different Species. While some are more common than others, all are equal parts of galactic society, and migration from world to world means different Species are equally likely to be found on any world.
When making your Planetfall character, pick your Species. This does not define your origin world - which is more likely to influence your character's culture and roleplaying choices - but does give you physical characteristics and quirks. Every species except for Human has a positive and a negative quirk (Humans only have a positive one) which all characters of that Species receive.
As ever, there is no requirement to costume your Species, but costume element suggestions are provided here for the adventurous.
The Species listed here are not a definitive list - get in touch with the Refs if you have a Species idea you would like to play (subject to approval).
