Nadia

Nadia is the quantum computer Watt Bakradi built when he was just 13 years old at a MIT summer program. When the professor in charge caught Watt building her, she demanded Watt destroy Nadia.

Instead, Watt hid her in various places into he came back home to the tower where they began their hacking career.

When Watt thought a client was on to them, he took Nadia to a six-fingered doctor with a reputation of doing illegal surgeries and had Nadia surgically fused to his head, right above his right ear.
