Earth 34

Origins
On this Earth, for whatever reason, humans never evolved. Instead, several different sentient species evolved, including the Treelings, the Foxen, The Octons, and the Sheep-herd.
The Treelings
The Treelings are a race of sentient tree-creatures. They are the most academically advanced of all the sentient species, known world-round for their arts, science, and culture. They live in the Ancient Forest, a city for them made out of the ancient still-living Treelings. Treelings start out as saplings, with full mobility within the city, who survive by tapping into the life energy of the ancient trees. Then as they get older, they continue to grow, until they can no longer fit into the buildings made up of the older trees, at which point they step beyond the current boundaries of the forest, take up roots, and lose their mobility. They never lose their ability to talk, so they often choose what kind of building they would like to be made into. The Treelings are religiously reverent to their elders because of their wisdom and their being the source of their life in youth. The Ancient Forest is the intellectual and cultural hub of Earth 34, and many of the other species come to visit. The Treelings are known for their poetry, theatre, novels, philosophy, and science. Some of the less benign Treelings use their technological superiority to manipulate the less developed species who come to visit.
The Foxen
The Foxen are a sentient species of fox whose society is based upon capitalistic competition taken to the logical extreme. They are at war with the Sheep-herd, their ideological opposite. Because they are so hyper competitive, they exist only in several city states, scattered across the globe and do not have a single unified state.
The Octons
The Octons are sentient Octopi who have formed an industrial society on the coastlines of the major landmasses.
The Sheep-herd
The Sheep-herd is a society of sentient Sheep who live in one big communist bloc. They are at war with the Foxen, their ideological opposite. Their weakness lies in the fact that they have little incentive to innovate, leaving them technologically bested by the Foxen.
