The Harbingers of Cyriss are a battle force of Aeons. The heart of the Cadre is its two squads, the Exalted Paragons and the winged Antecessors Eternal. The Paragon Commander solo who leads the Exalted Paragons in battle also serves the Empyreans as a Fury-channeling weaver. Unlike the Saber servitors, who serve the Empyreans as expendable soldiers, the Aeons are ancient spirits too valuable to risk losing in battle. To save their spirits from this ignominious fate, an Eternal Metator Champion attachment leads the Antecessors Eternal into battle. The Metator collects the souls of those who fall in battle, generating vast amounts of arcane energy in the process.
- The Aeons are the ancient warrior elite of the Empyreans. They are much more powerful and hardier warriors than the robotic Saber legions.
- The models in the new Cadres are designed to work together and support each other in play.
- The Eternal Metator solo champion is capable of harvesting Arc from fallen Aeon models and can return destroyed Aeons to their squads.
