Tritovore
Tractators were giant invertebrates that could control gravity. They were mindless creatures who needed the Gravis to act intelligently.
Biology
The Tractors were insect-like in appearance. Their backs were covered in oyster-coloured chitinous scales. They had two long antennae on their head which they used to control gravity. Tractor mucus was green and had a granitic nature.
Their leader was the Gravis and it acted in a similar manner as a queen bee and her swarm. The Gravis had darker skin, an external nose and larger ears. It was also the only Tractor who could speak.
Technology
The Tractors used scavenged machinery combined with parts of living beings to create machines.
