I can actually answer this one. Huntsmen get their full write-up in CtL 2nd Ed, starting on pg. 262.
In summary, the Huntsman
hunts. They have no other purpose or desire because the True Fae have scooped out their hearts to bind them to carry out their will and recapture escaped changelings. All but one of their Aspirations is replaced with the ones the True Fae gave them, which usually amount to 'get back that changeling I was sent after'. When it comes to appearance, Huntsmen can change how they look, but they have what's called a Panoply: a set of items that always are reflected on their person that are core to their identity. These are usually an iconic piece of clothing (a medal, a hat, an eyepatch, something recognizable) and a favorite weapon (an ornate sword, an old-timey musket, etc). A Huntsman is more defined by their equipment than their appearance because their self has been suborned by the True Fae that is using them.
Power wise, they're built very similarly to horrors from the core book, with a couple of exceptions and unique Dread Powers
- Have Wyrd instead of Potency
- Have a Glamour pool to fuel their powers
-
Can not use Contracts like a True Fae or Changeling, but can make Oaths
- Can do most of the dream and Hedge stuff that Changelings can do
- Their Virtue and Vice reflect the Title the True Fae gave them and their own repressed self respectively
- Innate powers:
-- Among the Sheep: Can take human form for 2 Glamour
-- Command the Herald: Can summon an animal buddy for 1 Glamour/hour, can see through it's senses and talk through it
-- Heart of Iron: Cold Iron is
not a Bane, despite them still being Fae
-- Hunter's Panoply: Gain 8-again when using their Panoply tools, but lose 10-again if they attempt to do an action where their tools could be used, but they don't (or can't) use them
