Just an idea I had for background of Vulpes Chthonae (©  mythril_blackpaw ) - someone who would be responsible for guiding people (not as a leader - but with advice), keeping machines at good condition and performing ceremonies.
Tech Matriarchs are literally "more machines than foxes" as their racial affinity for augmentations is so great that at some point most of their body is replaced or supported by machinery.
If attacked - they are all but defenseless: they are faster and stronger than typical Cog Foxes due to mass augmentation, also they have access to more advanced technology of past.
