@viola1588 Hello! I'm glad you enjoyed it! "Little Thief" is based largely on Changelings. In Folklore from all over Europe, Changelings are Fairy children swapped for Human children. Some Changelings are found as "orphans"; either way, once a Changeling entered a home, it usually caused mischief and misfortune. There are dozens of stories and "actual accounts" of Changelings here: http://www.pitt.edu/~dash/britchange.html.
The more you dig into the subject, it's pretty obvious a lot of documented "Changelings" were most likely children who suffered Dwarfism, Autism, or a number of other disorders that went unrecognized at the time. That list is good reading for anyone with an interest in the subject, though, whether you believe the first-hand accounts or not. :D
