During the 14th century, the planet Ventax II faced a number of crises, including war, and pollution. During this period, the Contract With Ardra was drafted, stating that Ardra would provide the Ventaxian people with 1,000 years of peace and prosperity, and at the end of which, the planet and its people would become her property.

Starfleet officers also continued to refer to her by the name of Ardra.
