A former Separatist ST series tactical droid, Myrmex was known for her devilish tactical prowess, securing several separatist victories with minimal losses, as well as knowing when to cut said losses when a cause was deemed inefficient, impractical or taking an undue amount of risk. While not as stubborn as her predecessor T series droids, on several occasions, she lambasted her superior's lack of tactics or their questionable orders to their faces on several occasions. This ultimately led to the relegation of her to smaller operations, where such was less likely to question whether a show of force was, quote, "A means with which your organic inadequacy over the volume of [her superior's] reproductive anatomy."
Said relegation meant that she was the commanding officer over the defense force of a Mk2 Droideka factory, which was subject to a surprise attack by republic forces. In order to avoid her destruction, and due to the failure of all other contingency plans, and the jamming and destruction of communication with high command, she had installed her software into a jury rigged mk2 droideka body, and ejected herself amidst battle debris to drift for an indeterminate amount of time before being hopefully picked up by seperatist forces seeking to reclaim their lost asset.
Unfortunately, said forces never came, due to the ending of the Clone Wars with Order 66.
After an undetermined amount of time drifting in space on low power, and only able to run battle scenarios to predict how the incompetence of her "f[beep]king meatbag" commanding officers lead to this, she eventually was picked up by a group of scavengers, sold to some jawas, and lastly ended up purchased by Thakba the Hutt. From thereon, she was utilized as a sort of security droid, though the notice of her modified database was taking note of - and an enterprising Thakba saw the potential for sending her to shepherd encrypted data in addition to said body-guarding.

Endure and preserve self's knowledge, expertise, battle prowess and tactics, as well as find a means to put them to use.

Thakba the Hutt's service, having been bought from the Jawas and fitted with a restraining bolt.

The scavenger who picked her up.

Heavily modified Mk 2 Droideka body, complete with a black paintjob, grasping hands, and a modified processor containing her AI. A tendency to the calculating and the crass. More to be determined through gameplay fleshing out.
