I'm setting up this thread as a result of a discussion in the recent Q & A, where several readers volunteered to collate some general information about the Psy/Changeling series ie. things like when a character was first introduced, how he or she is related to other characters, and any other relevant facts.
So this thread is for things already established. If you'd like to speculate on future books or storylines, swing by the Hostage to Pleasure Spoiler Thread.
Everyone is welcome to join in! :)
