Teneebia

Teneebia (also known as Alpha Comae Berenices) was a star with an associated system and the namesake of the Teneebia sector of the Alpha Centauri sector block in the Beta Quadrant. Two bodies in the system were inhabited, the moons of a destroyed planet. The Teneebian species was native to the system. They were members of the Federation by the late 24th century. 

Planets and local bodies
The Teneebian system consisted of a primary star and several planets. The famed Teneebian amethysts, unusually large crystals, could be found in the caves of Teneebia Alpha.

The Teneebian moons were the only inhabited bodies in the system. The planet they once orbited was destroyed eons ago. It remains made up a dense asteroid belt. The Federation tested its transwarp network near the asteroid field and destroyed several thoron-rich asteroids. 

History
The native Teneebians were warp-capable since before the 2150s. By 2378, they had joined the United Federation of Planets. 

In 2409, the Federation opened a transwarp gate in the system's asteroid field to test the technology. Starfleet deployed a minefield developed by Doctor S'larin and his team at the Sierra Outpost II to keep the Tal Shiar from using the transwarp network to launch strikes at Federation coreworlds. The Romulans attacked while Starfleet deployed the minefield but were repelled.
