Ab-Tzenketh (known informally as Tzenketh) is a planet, the sixth planet of fifteen in the Tzenketh star system of the Alpha Quadrant's Tzenkethi sector. Ab-Tzenketh was the homeworld of the Tzenkethi civilization and the administrative center of the Tzenkethi Coalition. The Tzenkethi homeworld is located in an area of the Alpha Quadrant's Federation expansion, with Starbase 621 and the planet Mizar not particularly distant. (ST reference: Star Charts; Decipher RPG module: Worlds; Typhon Pact novel: Rough Beasts of Empire)
Ab-Tzenketh is orbited by two moons known as Vot-Tzenketh and Lem-Tzenketh. (Typhon Pact novel: Rough Beasts of Empire) One of these moons was commonly known as the Royal Moon, believed by the average Tzenkethi citizens to serve as the home of the Autarch of the Tzenkethi Coalition. (Typhon Pact novel: Brinkmanship)
- Brinkmanship does not identify whether Vot-Tzenketh or Lem-Tzenketh was the Royal Moon.
Ab-Tzenketh is also encircled by a virtual shell of artificial satellites so dense that it obstructs the moons' reflected light during nights. These satellites serbve a number of functions, including orbital defense, external sensors, communications, global positioning, transporter management, weather control, and disruption of foreign sensor and transporter systems. (Typhon Pact novel: Rough Beasts of Empire)
Ab-Tzenketh has a watery surface, with several island continents representing the landmass of the world. In particular, the Tnectish continent was the cradle of the planet's sentient civilization, and remained the location of the planet's capital in the 24th century.
Ab-Tzenketh is a cool world with expansive ice caps, although the habitable portions are not considered to overly cold planet. The early Tzenkethi civilization saw the icy Tfenpthi Mountains to the north as a goal, with the crown shape of their peaks representing an almost spiritual goal for their people.
