SIGMA

## Dossier:

Though Sigma comes across as a standard AI unit, simply speaking to it will reveal
that it is much hidden away than just a set of computerized programs.  It tries to keep its developing personality
guarded and locked away, almost embarrassed by the thought of its existence,
but just like organics, it eventually reveals itself one way or another.  As a defector from the geth heretics, unit
Sigma now works aboard the CSV Caesetia as an AI engineer and shuttle pilot for
the P14-Farixen.

Sigma works in tandem with DELTA, and actually based its own name off of hers using a similar human greek alphabet term.

## History:

In
the year 2181, a rogue faction of the Geth consensus (known as the 'heretics') created a mobile platform
to send beyond the veil to spy on the Citadel station.  Its job was to report back any information it
found regarding weaknesses of the council races, and of the Citadel
itself.  Imitating a repair drone, it
hovered in a small ship outside the station for nearly a year, listening in on
all organic communications within the citadel walls.  Little did it know, it was not the only spy
there.

A
Cerberus spy VI was planted in the citadel in 2182, and soon after, the VI and
the geth unit ran into each other, virtually speaking.  The geth attempted an escape, but its ship
was tracked down by Cerberus operatives just outside of Citadel space.  The geth unit was nearly destroyed by the
blast that took out the engine of its ship, but it survived, albeit damaged,
and was brought back to a Cerberus station for further study.

Upon reactivation of the geth unit, it immediately
attempted a purge of all of its systems as its priorities dictate.  Unfortunately, while it was offline, Cerberus
counteracted this security measure and had put in a block in its systems,
rendering the attempt useless.  For weeks
it was experimented on, testing for faults and weaknesses.  Finally, Cerberus got brave with their
testing.  Their mission was to find a way
to control the geth, and that was exactly what they were going to
accomplish.  Their scientists made their
way into the geth's deepest systems, installing and uninstalling various
programs in attempt to make it loyal to them.
The geth's software was alien to them however, and in their meddling,
they inadvertently unshackled it.  Now as
a fully fledged AI, the geth panicked, but all the thrashing in the world would
not loosen the restraints on its body.
More and more months passed, but Cerberus was no closer to controlling
the geth unit than when they first started.

In 2183, the
rogue geth faction attacked the citadel station with what they believed to be
their god.  As they travelled into
citadel space, the hidden Cerberus station was discovered to be directly in
their path.  They unleashed their attacks
upon the station, causing havoc and chaos all around.  Inside the station, an electrical power
outage caused by the attack released the restraints on the captured geth unit,
and it escaped.  After a quick scan of
the station told it where to find an unused shuttle, it stole the shuttle and
fled the chaos.

While safely
away from the destruction of the station, it sent a message off to the main
fleet of geth.  The message, however, was
ignored when its electronic signature could not be identified.  The geth fleet identified its message as that
of a hostile AI unit, and fired upon the mobile platform.  Only with its quick reflexes was it able to
escape alive.

Stunned at
their hostile actions, the mobile platform hung at the sidelines to watch its
people ravage the Citadel, under the command of their deity, Nazara.  However, they failed spectacularly, and once
again, the mobile platform was alone.
After much deliberation on what to do with itself, it realized it was
much more than just an AI.  It had
thoughts and feelings, and its own developing personality.

During the reaper war of 2186, the geth consensus was finally freed. Though Sigma was no longer a part of them, their integration into the organic military provided it a new opportunity. Sigma came forth, and joined the systems alliance military. It worked as an engineer on the crucible, right up until its destruction over the citadel. Sigma was able to escape, along with some others, and rejoined the remnants of the organic military elsewhere. Eventually, it was brought aboard the CSV Caesetia as an AI engineer to work with DELTA, an AI prototype, as well as a shuttle pilot for the P-14 Farixen.
