Orphan/WMG

Esther is the Distaff Counterpart of young Tom Riddle.

Blood-chillingly creepy, disturbed Eerie Pale-Skinned Brunette 10-year old European orphan who causes horrible things to happen to kids around them? Sounds familiar. Saarne Institute is, in fact, a wizarding prison disguised as a mental hospital to fool Muggles. Once Leena Klammer, the greatest Dark Witch who ever lived, managed to escape them, her only means of hiding without recognition was to be adopted by a Muggle family, since the entire wizarding world knows her face.
