Clades

Overview
Clades are species that existed, or may have existed at one point but have either been lost to history or have been driven to extinction by the fires of war. They are all heavily genetically-modified, each clade having vastly different biology than the other. The Empire was extremely stratified, there were various clades with many different morphs within each clade.

Different clades cannot reproduce with each other, if they can sexually reproduce at all. Different morphs are able to reproduce sexually with each other.
