Before even the Dinosaurs...

Fabulous Dimetrodons defined wetland fashion. Behorned Xenacanthus sharks deftly negotiated sacred treaties. Nautiloids and Ammonites plumbed the deepest of philosophical depths. Thrinaxodons and Broomistegas cooperatively developed sophisticated aquacultural techniques. These paleozoic folks learned well the values of peace, respect, cooperation and communication.

Then, or course, Humans came and the big bullies just took whatever they wanted.

Very Pretty Paleozoic Pals: Permian Nations is a setting, or Sphere, for Troika! RPG. An incredibly ancient and positively adorable fantasy land.
