I don't think he's referring to Leanhaun Sidhe?

Looks pretty good, although I'm not sure how Awe-inspiring little goblin children would be. "Toiling forever in faerie mines" is actually straight up the description of what the Wizened (a subtype of Changeling) wind up suffering. Or some other more creative enslavement, like the one I once played who had to replace everything on the library's shelves just in time for them to be knocked down. Et cetera. That kind of thing.

Anyways, as a minor comment: amusingly, changelings in Changeling actually do have changeling doubles. For some reason this is instead called the fetch. Whatever. It's made of sticks, mud, and enchantment and many changelings go and run down their fetch and kill it. However, it has for all intents and purposes been living your life since the moment you were abducted... and is in some senses more human than you are, or at least no less than you, now that you're a soulless faerie monster. It also knows what you are and has defense mechanisms against you killing it, which only really trigger once you return to the real world.

As I recall it is less effective in stopping other people from killing it, but then it's dead, and that means you're dead, and you still can't return to your own life without lots of questions, so yeah.
