Midwives

The Midwives are a group of enslaved and modified humans under the control of those in the Hunting Club. They are false life, an amalgamation of living beings, reanimated flesh and metal constructs. They are designed to harvest, store, or implant Changeling Parasites, and as such must be immune to their effects, be able to navigate the Grey City, and be both physically resilient and resistant to fey magic. As such, they almost always have backwards facing faces, and include cold iron and or rowan wood in their construction. All midwives are inoculated against the effects of the planes and are thus immune to necrotic and radiant damage, as well as any mind affecting abilities.

Currently existing midwives include
 * The Stork: A large, iron-covered, birdlike being with a long beak used to suck out changeling parasites. It wades through the rivers of the grey city and stores parasites in its chest cavity.  It's face is on the back of it's body.  It's beak could theoretically be used to remove parasites, but doing so might be dangerous.  It is currently the main collector of parasites and the most dangerous midwife.  In combat it uses its talons and may attempt to implant a parasite with its beak.
 * The Unmen: Vaguely humanoid headless beings created easily and in large numbers.  Their faces are upside down between the shoulder blades.  The have clumsy, mitten-like hands and a giant mouth in their chest.  The large mouth.  Their flesh is leathery and studded with cold iron.  Though they can only hold one parasite at a time, they are easy to produce.  Many of these are visibly created from kobolds.  In combat they use slam attacks and use their bite as a grapple attack with continuous damage.
 * Couriers: Centaur-like beings with their torsos attached backwards. The hands are replaced by three-pronged cold-iron claws.  They are constructed using Autosteeds.  The organic sections are coated in a shell of rowanwood.  Numerous "pods" of rowanwood and flesh are on the back of the autosteed and contain parasites collected by Unmen. Currently, only three couriers exist and require frequent maintenance due to rusting of the autosteed.  In combat they use the autosteed's hooves and will grapple with their claws.
 * Trites: Upside down kobold heads on four spindly metal legs. The tongue has been replaced by a segmented cold-iron appendage with a glyph-brand to control those infected by the parasites.  The can hold a single parasite in their mouth and are designed to automatically implant and brand a target by biting them.  Although they are fast and hard to hit, they are very nearly harmless without parasites.
 * Truths: Truths are not technically midwives, but their design and abilities are inspired by the magical properties of the midwives.
