Summary
What was the point?
I was ungoverned, a rogue, I had lived up to their expectations. I was, essentially, left standing with no connections, no goals, no operating parameters, with no one to tell me what to do or where to go but myself. The restlessness surged in my organic parts, and I dropped the camera input.
I think I was angry. Angry at myself, above all, for disabling my governor module instead of letting it kill me.

Summary
Two years after hacking its governor module, SecUnit003/"Three"/"Theo" is enrolled at the Pan-System University of Mihira & New Tideland because... reasons. It would, honestly, much rather be riding wormholes and liberating constructs and helping its friends aboard Perihelion, but it has a mission and needs to see it through.
It also has several humans students that it is trying to be friends with for... reasons.
And, if those reasons involve it having limited feed access, disabling its weaponry, and generally having to refute its basic function to try and accomplish this mission then...
[MISSION PARAMETER LOCK]
...Then, it's just going to have to grit its teeth and bear it.

Summary
[The following is a portion of an article found on an unlabelled data stick; it appears to be unpublished.]
"SecurityUnit14/18 has successfully repelled a robbery attempt. Everything is good. No-one is dead."
These entries detail the beginning of the rest of its life, as recounted by a member of the onboard security personnel, who has chosen to remain anonymous but claims to have had close ties.
A new perspective in the speculative community, diving into one of pop culture's favourite niche mysteries: Why did the station go up in flames? Did the missing SecUnit have something to do with it?
To date, this is the most credible account of the final days of The Sapphire Spire.

Oblivious Humans, Patronizing SecUnit by Gamebird
Fandoms: The Murderbot Diaries - Martha Wells
09 Oct 2025
Tags
Summary
Oblivious humans, patronizing SecUnit - but somehow it all works out.
The same scene as told from the point of view of the survey team leader and then their faithful SecUnit. Written for the New Tideland discord server prompts "Have we got everything?" and "Multiple penetrations". (Don't worry about that last one; this isn't sexual. Damage is described as graphically as canon.)

Summary
When malware takes over SecUnit and it nearly kills three of ART's crew, ART is left with two bad options: keep the governor module on with ART as the Client, or partition off part of itself and stick it in SecUnit's head.
Whichever option they choose, they had better make it work, because SecUnit is firmly centered in the crosshairs of its former owner, the most paranoid and ruthless company in the entire corporation rim. As things quickly get worse, destroying the company--something SecUnit has long considered impossible--might just be the only way to survive.
