i need to know the neurosurgery lore... that sounds so cool
Servitors equip their Wards with implanted filaments that slide into the spinal cord (in a similar method to placing a spinal cord stimulator) as well as implanted filaments that enmesh the vagus nerve and its' branches and implanted filaments that run along or within key areas of the brain to assist with inducing states of joy and keeping Wards pain-free as they age, as well as for those Wards which may be very... tricky. Filaments placed within the brain (in regions like the thalamus and midbrain) allow direct control of chemistry on a level that exceeds tilting, silent and untraceable as anything but the brain's own signals (tilting without filament placement often feels like taking one long dose of MDMA and can cause neurotoxicity after years).
They do so with surgery arms that are extraordinarily precise within their 'end effectors', the ends so numerous, many, and small that they may slip between cells without bursting the walls. To the human eye, it looks like spun gossamer thread that stands stiffly on end, capable of turning in unison to glint light. These tiny end effectors can break off and be directed to perform individually, igniting similarity to what one may refer to as 'nanobot[s]'.
The surgery takes place in a specially constructed medical bay room devoid of bacteria or yeast (no death by candida infection following placement!). Wards are vigorously bathed before surgery takes place (they may even need to be shaved, depending on the status of their hair - scalps are difficult to ensure absolute, infallible cleanliness) Eyebrows, chest, beard, leg, and crotch hair will be shaved. The Servitor most likely to do the Ward's surgery is their own Servitor, as Wards frequently build very strong bonds (whether chemical or actual) or romantic attachments.
A Ward must remain in a semi-conscious state during surgery, as they must continue to provide feedback to ensure proper placement and prevent accidental paralysis or damage. Wards are often heavily tilted during surgery to spare them the rigors of its' duration and unpleasant pressure sensation during filament insertion.
Used equipment must be discarded following successful operation lest the Ward requests its' continued presence...
...some Wards claim that the feeling of tiny 'arms' slipping past the skin of their lips is 'like kissing' (while infrequent, Wards may occasionally bite, kiss, or pet the arms post-operation).
