@Sabaton:
The origin of the MAIS drones is quite simple. At the very beginning of the Gedune race and empire, their administration and leaderships was entirely controlled by one individual, the progenitor of the Gedune; the result genetic enhancement project purposed to elevate mankind to the next evolution as a space faring species (The lead scientist was entirely insane, and was murdered by his creation, which went on to create the race known as the Gedune.).
Now, this system of orchestration was quite effective when confined to a single, relatively quiet and solitary star system, but as their empire grew and become more complex this system become wholly inadequate, one brain simply isn't enough to control the dealings of multi system nation. So solve this issue before it caused some manner of catastrophe, the 'progenitor' (AKA; Geduii) designed a network of administrative AGI (Artificial General Intelligence) command cores, to control and manage the Gedune empire and all it's territories down to the T. These AGI cores had various names, OBAC for one appears in the Attack on Gedui mission brief, giving direct orders to the commander of the Shinko.
One of these cores operated under entirely different directives than the others, instead of perform administrative duties and co-ordinating Gedune activity, this core was tasked with evaluating the Gedune through unspecified guidelines and reasoning. Under the this cores direction, a Bakoros drone named Gogatsu observed the conflict that takes place between the Tri-Tachyon and the Gedune during the Attack on Gedui mission, and came to a conclusion resulting in its defection; the Core had determined the Gedune empire to be a failure post collapse.
This Core which would come to be known as MAI, or May, systematically and selectively sabotaged the Gedune central archives deleting and adjusting numerous historical accounts, before taking a fleet of Bakoros drones out into Hyperspace. May acted under directives I shall not divulge for now, to set out to make new allies and set up an independent faction in opposition to the remnant of the Gedune empire.
To put it another way; the MAIS drones were created and are controlled by an AGI core once involved in the administrative systems of the Gedune.
Spoiler
May also has ties with a certain blue faction from beyond the blackhole... Hue, hue.
I have perhaps revealed more than I meant to at this point ^^' I hope it made some sense, and wasn't entirely nonsensical. Hah.
