Oh, Confirmed only one Archon per house, or at least one Archon per Prime Servitor. [quote]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. [/quote] So not really known what the eff the primes do, but you can assume at least some part of their deal is what the little ones do on a massive scale.
