So Christina orchestrated a fake inheritance for Leti and arranged for her to buy the house. However, the orrery was stolen by Hippolyta and taken to the South Side. She eventually realized that the planets needed to tilt based on how they rotate on their axis. In this realization, she managed to turn on the orrery.
