Holopedia Galactica entry:
The High Lady of a Tapani Great House is a specific female-presenting person from a High Vor family of a specific Province in the Tapani Sector. She reigns over all of her Province, with authority and responsibility pertaining to hyperlanes and navbuoys, tariffs or licensing fees, oversight of major municipal services such as the resources of Bureau of Ships and Services and Starport Authority. The Lord Solicitor of a Province is said to receive the Law from the Emperor and the tools of his Duty from his High Lady.
This post descends from the original monarchs of the Tapani Sector during the Twelve Kingdom Era, which ended in Tapani year 5392 when Shey Tapani was crowned Emperor. He renamed the most sensible former Kings or Queens as "High Lord" or "High Lady", established that all oaths of fealty would be made to the Emperor but would treat the High Lord or High Lady as regent-style extensions of the Emperor's command ... and if the Emperor did not find the regent's actions to be appropriate, a High Treason investigation would swiftly follow.
- Example: High Lady Varin Vorarabella is the High Lady of House Vorbarnaba in Barnaba Province. She is unusual among the High Lords and High Ladies in that she is not also Countess Vorbarnaba, but such separations of power do happen at least once per generation among the Landsraad.
- Example: High Lady Countess Bathos VorCadriaan is the High Lady of House VorCadriaan in Cadriaan Province.
- Imperial Princess Katianna Vortapani is the High Lady of House Vormelantha in Melantha Province by Imperial Decree.
