32.)Cardasia
Formal name of the empire's home system star and, at least informally, its home world. It has at least five planets.Cardasia III: World where Zek obtained the Bajoran Orb of Wisdom from a contact, his last stop before heading into the wormhole to seek future advice from its builders. Cardasia IV:Class M home to the Hutet Labor Camp, where Major Kira and Chief O'Brien rescued the dozen or so Bajoran prisoners of war still being held there, including Li Nalas.Cardasia Prime:The formal name of the Cardassian homeworld -- a world other than the third, fourth or fifth planet of the system -- although natives often informally drop the "Prime." Its capital city is awash with giant and continuous state-controlled messages extolling self-sacrifice, order, and subservience to the government -- with a characteristic emphasis on the family and children; the central prison is located there. Another city is Lakaria City. It is only one of dozens of worlds devastated economically with the old order's collapse and the Klingon invasion. An ancient Bajoran solar sailor's crash site on the planet was kept secret out of pride until Commander Sisko and Jake's historic trip recreating the accomplishment in in 2371. Cardasia V:World that hosts a museum where Quark's cousin Kono once stole bone carving artifcats, coming to Deep Space Nine circa stardate 47603 to get help fencing them .

No info(Identified by Lt. Nikki)

  34.)Cestus III
A world that was disputed by the United Federation of Planets and the Gorn in 2366 is now a clear Federation colony and the site of baseball's revival, located on the far side of the Federation from Deep Space Nine; a subspace transmission alone takes two weeks. One community is Pike City, where Yates' youngest brother lives and plays on the team.

  35.)Cheron
Site of a battle with the United Federation of Planets considered a "humiliating" defeat by the Romulans, according to Admiral Jarok. It led to the creation of the Neutral Zone and thus likely climaxed the original Romulan War in 2160. By coincidence, it is also the planet or namesake sector of the long-dead world where a group of two advanced races destroyed each other over racial bigotry, not encountered by the UFP until 2369.

  36.)Chin'oka System
A sector in Cardasian space that is a area at first controlled by the dominion and then controled later by the Federation. It is a place of many titanic space battles. Strategically important planetary system that in late 2374 was held by the Dominion during their war with the Alpha Quadrant powers. The Chin'oka System was the site of a decisive battle in which Federation, Klingon, and Romulan forces destroyed a sophisticated Cardassian automated defence system, landing ground troops on Cardassian territory.((Info Provided by Lt.

  37.)Cosmic String Fragment
Highly accelerated interstellar gases; one that attracts two-dimensional instinctual beings is 107 km long and one proton wide, with gravitational fields as powerful as a black hole or 100 other stars. It emits a characteristic set of subspace frequencies as atomic particles decay along its event horizon, duplicated with the U.S.S. Enterprise NCC-1701-D's parabolic dish to confuse the two-dimensional and halt them long enough to break free of their graviton field wake.

  38.)Crystaline Enity
Origin: space. A massive and unique lifeform, delicate in appearance while blindly and insatiably feeding off the life-force of beings and even planetary resources. It could destroy a world in just minutes with its pulverizing energy-beam conversion process, working much like an electromagentic collector. Somehow contacted by Data's brother Lore in 2338, it is known to have wiped out the Omicron Theta colony and its 114 scientists, then 11 more worlds ending with Melona IV until its destruction nearby in 2368. Ironically, just before its death it showed signs of sentience and understanding the different orders of life-energy it had been consuming.(Info by Nikki Bray)
