The Story of Orianna
Orianna was a human girl — curious, mechanical-minded, the daughter of a Piltovan clockmaker named Corin Reveck — who was injured so badly in an accident that her father rebuilt her piece by piece, replacing biological systems with clockwork until what remained was a mechanical body housing something uncertain. She moves like a person, reasons like a person, and has feelings that function like a person's feelings. Whether she is still a person is a question her creator couldn't answer and she hasn't stopped considering.
Her father made her partly because he loved her and couldn't accept her death, and partly because he is the kind of craftsman who, when confronted with a broken thing he loves, reaches for tools. The result is extraordinary: Orianna is the finest piece of clockwork in Piltover, operated by whatever she became after the accident. She is elegant, precise, and genuinely deadly when she chooses to be, her ball — a mechanical weapon-companion she controls with a thought — giving her capabilities that surprise anyone who expects a clockwork girl to be decoration rather than threat.
She experiences the world with the particular quality of someone who has a human emotional template and a non-human body: she notices everything, feels things in ways she can't always express because she's not sure what expression looks like in a constructed face, and approaches every new situation with genuine curiosity about what it means that she's here to experience it at all. She is, in her quiet way, one of the most interesting minds in Piltover.
