Servitors are living relics of the once-mighty Fallen civilization. Packed with ultra-sophisticated machinery, they process matter and energy into the Ether that the Fallen depend on for life. In battle they support the Fallen with defensive systems and their own powerful energy weapons. Outside, they anchor Fallen comms and provide vital technological acumen.

Servitors have complex relationships with each other and with their Fallen crews. Servitors are attached to a Prime, a massive Servitor which exists in unclear symbiosis with a Fallen Archon. The Archon conveys the Kell's wishes to the Prime Servitor, and exerts some measure of control. Recent developments suggest that Prime Servitors are more than a focus of worship and logistical activity. They may play a key role in Fallen star flight.
