Each changeling is comprised of two halves: the mortal seeming, which represents the changeling's human facade, and the fae mien, which constitutes their true, hidden faerie self. The self born in the mundane world and raised as a normal human is the mortal seeming, influenced to varying degrees by the dormant seeming that does not emerge until Chrysalis takes place for most of the commoner kith. For sidhe, the fae mien usurps the resident mind/personality/soul of the mortal "host", retaining memories when convenient.
