This page clears up any confusion about who the Aeta is currently at war with.
THE DELLERS: The Dellers are clones of a man named Jake Deller. They are the Aeta's primary enemy.
THE ECOTERRORISTS: The ecoterrorists are humans that have bounties with the Aeta. The Aeta used to primarily fight them, before the Dellers came into the story.
THE REBEL ORDER: The rebels are quadized animals that betrayed the Aeta to join an evil faction that works with Dellers, Ecoterrorists, or anybody that gives them the opportunity to kill quads.
