Background information 
 Lines from  and  indicate that the time of Kahless was "a thousand years ago", i.e., apparently implying the 14th century. However, "Rightful Heir" mentions the monks on Boreth had been awaiting Kahless' return for "fifteen centuries", i.e. five hundred years longer. This would also be in accord with the Sword of Kahless being dated to an age of 1,400 years in . Furthermore, a scene cut from "Rightful Heir" had Data specify Kahless' death as 1,547 years ago, which would place it in 822 AD.

 According to , the Ventaxian civilization benefited a thousand-year period of peace and prosperity. Before that period, they suffered from environmental pollution, severe overcrowding, and constant warfare. According to legend, the Ventaxians made a pact with a supernatural being named Ardra. In return, they became Ardra's slaves and had their riches given to her after those thousand years of peace. In 2367, an interstellar con artist deceived the Ventaxians into believing she was the deity in order to reclaim this prize. If the Ventaxian year is close to the Earth year, the beginning of this new era on Ventax II would be set in the 14th century.
