Psi-Technology is the enhancement or extension of an Advent's mind... Able to amplify the power of a meager Archon ten fold... or give a Valeron the power to control his ship through mere thought process alone...
Everything from the common house complex to the grandest of starbases, and to some even worlds and people, are controlled by powerfull Advent minds, though an Advent in control of any object or being may not die along with the destruction of his controlled object or the death of countless, he will feel it, the more disciplined the mind the more sanity is retained with the death of I.E. a Valeron's ship to the commanding valeron(assuming the valeron jettisoned).
The Advent ships / fleets / starbases are armed with the "state-of-the-art" psi-technology from its weopon systems to its movement depending on how powerfull the valeron is, though a capital is crewed with thousands of people, their may only be about 20 or even 10 archons / valeron controlling the ship systems all an extension of the mind...
The Anima, are merely hollow shells, they are only expensive machines/robots without a mind, not easy it is for the common psycher to manipulate more then one anima at a time, for each anima is a peace of in a sense the concious of the Advent who controls them, controlling to many at once and the advent will loose the sense of who they are as they attempt to repeice their minds. The max controlled by any Advent is limited to 5, a squad force on the ground has but one "live" advent soldier/commander controlling various sized squads of anima or a wing commander to a bomber / fighter squadron, 5 is the limit due to complications with spliting the mind 6 times as its reserved for their own body, when it passes 6 the body dies and depending on how powerfull the Advent controlling is he/she may wind up to be an anima permenantly. Note: These rules and possibilities do not limit some, as it is said the Empress's entire gaurd of thousands are controlled by her thought alone.
