From Introduction:
The green (singular and plural) are a race of intelligent plant life that may well be the oldest intelligent society. According to their creation myths, the green are the first children of the Earth Mother raised up from soil and seed. The green prefer natural surroundings and are contemplative philosophers. They claim to be immortal, but many have died from disease, fire, magic, and physical trauma.
There are many variations within the race of the green. While skin color, foliage shapes and sizes, and physical size vary widely, the green can most easily be divided into two subgroups based on climate: the decians and the pinians. These subgroups are merely a means for other races to categorize the green and do not represent actual subraces.
