About as well as demon the fallen would transfer to dark age, I imagine. Though I agree dark age fae was a lot better than changeling. But are the fae immortal? How does that work with their hosts? I'm still trying to figure out how the host thing works with aging in demon. It says they age, but are immune to decomposition so they don't grow weak and useless... so do they age to their peak were the body stops growing and making new cells then stops aging?
