Wammy's House (located in Winchester, England) is one of many orphanages established by Quillsh Wammy (aka Watari). Founded after
World War II, Wammy's House began as a training facility for children with
exceptional intelligence and skills. After the success of the detective L, the motive of the school was to raise children to be the successor to the original L. None of the children refer to (or know) each other by their real names, instead using aliases, mostly patterned after letters in the alphabet.
