Amusement Park Planet150 The world was used as a huge amusement park by an advanced alien species. Although the surface gave the appearance of an undeveloped world inhabited only by plantlife, beneath the ground were gigantic and highly advanced factories. Sensors could detect the thoughts of those on the surface, determining their innermost desire and then fabricating whatever was necessary for them to live it out. Even perfect simulations of real people could be created for visitors to interact with. The Enterprise crew visited the planet in 2267 for some rest and recreation, believing it to be uninhabited. They were initially perplexed by their experiences there but once the caretaker of the world explained the situation to them, the crew were able to have a highly enjoyable time.150 Shore Leave

Angosia III154 Planet which was applying for Federation membership in 2366. Captain Picard initially considered them good applicants, though Commander Riker regarded the planet as being too "stuffy". During the final stages of the membership application it emerged that during a recent war Angosia had modified some of its citizens to become the perfect soldiers, then imprisoned them rather than try to reverse the process after the war. Picard used the incident to delay membership until the situation had been resolved.154 The Hunted

Ba'ku188 An M class planet located in the Briar Patch. The planet had a ring system which was loaded with metaphasic radiation; the effect of this was to grant exceptionally long life to the inhabitants of the planet. It was the site of a Ba'ku settlement of about 600 people who had fled their original home world fearing that their species was on a path to self-destruction. The Ba'ku favoured a simple pastoral lifestyle, eschewing most forms of technology.188

Eventually a group of Ba'ku became dissilusioned with this mode of living and left the planet, with the result that they began to age normally. They dubbed themselves the Son'a. In 2375 the Son'a, in collusion with the Federation, attempted to harvest the ring system of the metaphasic radiation to regain their youth.188

Bersallis III suffers a period of massive firestorms every seven years, caused by solar radiation interacting with plasma in the atmosphere. In 2369 the firestorms came a year ahead of schedule and were exceptionally large and fast moving, threatening to overwhelm and destroy the colony and all within it. The Enterprise-D crew managed to erect forcefields to hold back the firestorm whilst the colony was evacuated, saving all 643 people there.

Beta III217 The third planet of the C-111 system, Beta III was home to a pre-warp humanoid species. Approximately 6,000 years ago the planet was wracked by civil wars, so much so that a leader named Landru created a highly sophisticated computer system to solve the problem. The computer was capable of "absorbing" a person, radically altering their personality in order to make them dedicated to peaceful coexistence. Unfortunately this had the effect of stifling their natural emotions to such an extent that some form of outlet was needed; the computer solved this by allowing periodic release during "festivals", in which the population was encouraged to run riot. In 2167 the USS Enterprise visited the planet; Captain Kirk determined that the computer, which had also dubbed itself Landru, was stifling the society rather than continuing it. He destroyed the computer, leaving some sociologists to assist the population in forming a society of their own.217 The Return of the Archons

All contact with the planet was lost in the year 2266, and it was feared that Deneva had fallen victim to an insanity effect which seemed to be progressing through the Galaxy. The USS Enterprise investigated and found that the planet had been infested by the Denevan neural parasites. The ship was able to eliminate the infestation.289

In 2381, Deneva was one of the planets attacked by the Borg during their invasion of the Alpha Quadrant. The entire population was wiped out, save for a few thousand who were able to evacuate before the attack.121 Amongst the death were Elieth, the son of Tuvok and T'Pel, and his wife Ione.263

Droplet263 The fourth planet of the UFC 86783 system - named as New Kaferia by the Stellar Cartography department on the USS Titan since the star was very similar to Kaferia’s star Tau Ceti - Droplet was a Léger-type ocean planet. It was Class O, subclass L1. It had a lower density than Earth but was larger, giving it about three times the total mass. Nearly half of that mass was water ice.263

Droplet had a metal core thirty seven hundred kilometres deep, surrounded by nearly three thousand kilometres of silicate rock. Above that was a mantle of high-pressure allotropic ice over four thousand kilometres deep. Above the ice was an ocean of liquid water some ninety kilometres deep.263

The planet was in an unusually wide orbit around the sun, but had a tropical climate due to the considerable greenhouse in the atmosphere combined with convection currents in the oceans which brought heat up from the bottom.263

Unusually for such worlds, Droplet was inhabited by a variety of life forms including higher-order life. Although there was no solid land, the surface was dotted with floating islands composed of a coral-like substance created by living beings.263

The USS Titan discovered Droplet in 2381, the ship's first stop on the exploratory mission which it resumed after the Borg crisis earlier that year.263

Dulisian IV299 Planet somewhere in the vicinity of Romulan space. In 2368 the Romulans fakes a distress call from Dulisian IV in an attempt to draw the Enterprise-D away from their planned surprise attack on Vulcan.299 Since the call claimed a failure of life support on the planet, it may possibly be an uninhabitable world which holds a sealed colony.

Dytallix B301 Also known as Mira Antilla V, this is the fifth of six planets orbiting the gas giant Mira in the Mira system. One side of Dytallix B permanently faces the sun. Surface temperatures reach 180 degrees on this hemisphere as a result. Mining took place on the planet for the Federation, carried out by the Dytallix mining company. Mining facilities are situated in the temperate zone between the day and night sides of the planet, but by 2364 these were deserted. There are no native inhabitants or life forms on the planet.301 Conspiracy

Eden257 A planet long thought mythical, which legend described to be a perfect paradise. Dr. Sevrin became convinced that the planet Eden was real and in 2269 he attempted to reach it by stealing the Federation space cruiser, Aurora, but he and his party were captured by the USS Enterprise. However, he was able to hijack the Starship and make his way to Eden, which lay within Romulan space. Sevrin was a carrier of synthococcus novae, and believed that living on Eden would cure him of the disease completely. However on arrival the planet was found to be lethally poisonous - every single plant was suffused with acid so strong that merely touching it for a few moments produced serious chemical burns. Dr. Sevrin and one of his followers, Adam, were killed attempting to eat fruit on the planet. The others were rescued.257 The Way to Eden

Eminiar VII169 An inhabited planet located in the NGC 321 star cluster. Eminiar colonised the third planet in their system, Vendikar, some time prior to the mid 18th century. Vendikar eventually turned against Eminiar and a war broke out between the two in 1767. The primary means of fighting was the use of long range transporters to materialise fusion bombs over cities; the destruction was so great that both civilisations were threatened with total destruction. As a result, the two societies entered into an agreement to conduct the war via computers; attacks would be carried out mathematically and casualties registered. Those designated as casualties would them report to disintegration machines for disposal. This allowed the war to continue on an permanently sustainable basis.169

Eminiar was in an important strategic location with regards to the Federation, and in 2217 the USS Valiant was sent to make contact with the planet. Unfortunately an attack was calculated to have destroyed the ship in orbit, and the Eminians were able to overpower and eliminate the crew in response. The Eminians resisted all further outside contact as strongly as possible, but in 2267 the USS Enterprise was sent to force the issue by making contact over and above their wishes. Again an attack registered the ship as a casualty, but Captain Kirk was able to resist all efforts at immolating him and force a breakdown in the system governing the war. Federation Ambassador Fox offered his assistance in negotiating an end to the conflict.169

By the 2340s, Khitomer was a Klingon world, the site of a colony. It was attacked by the Romulans in 2346. Thanks to the betrayal of the Duras family the attack was a complete success, resulting in the massacre of 4,000 colonists.364 The House of Mogh was almost destroyed in the attack, though the infant Worf was rescued by a Starfleet officer whose ship responded to the attack.365

Other Klingons were captured in the attack, and kept in Romulan captivity for decades afterwards.148

Only slightly larger than Earth's moon, the planet was originally class D until it was terraformed by the Andorians after they colonised it in 2052. The Vulcans became concerned that the settlement was a military outpost and claimed the planet in 2097, removing the colonists by force. It remained uninhabited until the Andorians landed a small force in 2152, prompting further hostilities. Captain Archer was able to negotiate a cease fire.428 Cease Fire
Pacifica301 Ocean world which the Enterprise-D was due to visit on a scientific mission in 2364.

Qo'noS363 A Class M planet, Qo’noS - rendered in English as Kronos - is the home world of the Klingon species and capital of the Klingon Empire.363 The planet was first visited by Humans in 2151 when the crew of the NX-01 took the Klingon operative Klaang back to his people.103 The co-ordinates of Qo’noS are 43.89.26.05415, placing it some 4 days away from Earth at Warp 4.5.103

Qo’noS had at least one moon, Praxis, which was a key energy production facility for the Empire during the 23rd century. The Klingons took insufficient safety precautions and over-mined the moon, which resulted in a devastating explosion in 2293. Much of Praxis was destroyed, producing a massive subspace shockwave and severely damaging the planet’s ozone layer and leading to increasing oxygen depletion. The planet was expected to become uninhabitable by 2343363, although apparently some way was found to avert this.442

Captain Picard visited Qo’noS in 2366 as part of Lieutenant Worf’s attempt to clear his family name. Although Worf accepted discommendation in a political deal to protect the Empire from dissolving into civil war, he and Captain Picard returned to the planet in 2367 to clear his name - and did indeed spark a civil war in the process.443

Quark would also visit Qo’noS in 2371 during his brief marriage to the Lady Grilka.192

In the Kelvin timeline, Khan Noonien Singh took refuge on Qo’noS after his attack on Starfleet headquarters. He hid in a deserted province of the planet, knowing Starfleet would find it difficult to pursue him there. Admiral Marcus ordered Captain Kirk to bombard the planet with long range torpedoes from the edge of Klingon space in order to kill Khan. Kirk disobeyed orders and instead took a small ship to the planet and captured him.444

The planet was divided up into various regions. The Ketha lowlands were the birthplace of Chancellor Martok, an area dominated by farmlands.245 Grilka was from the Mekro’vak region. 196 There were also many geographical features of note, including the Lava Caves of No'Mat, the heat of which could produce hallucinogenic effects in Klingons. Worf once experienced a vision of Kahless after spending six days in the caves. 148 The Hamar Mountains were home to Targs whose shoulders were used in the making of var’Hama candles.445 The Sea of Gatan was a body of water in which B’Elanna Torres almost drowned as a child.446 Kang's Summit was a location where Chancellor Martok once hunted Sabre Bear.447 The Kri'stak Volcano, and the nearby Lake of Lusor were also notable. According to legend Kahless forged the first Bat’leth sword by dipping a lock of his own hair into the lava of the volcano and then cooling it in the lake.417 The Skral River was noted in a Klingon drinking song which claimed that it once ran red with blood after a battle.446

Cities on Qo’noS included Qam-Chee, the site of a famous battle in which the Emperor Kahless and Lady Lukara stood against five hundred warriors - and, later on, jumped on one another ‘like a pack of wild voles’, beginning the greatest romance in Klingon history. 448

Quin'lat was another historic city. According to legend a great storm once approached this city; whilst Kahless and others took shelter inside, one Klingon remained to face the storm, determined to make it respect him. The man was killed, and Kahless noted afterwards that his act was more one of foolishness than courage.196

Tong Vey was yet another city at which a famous battle took place. Ten thousand warriors, led by the Emperor Sompek, conquered the city after a long siege. Sompek ordered it burned to the ground and every inhabitant killed. Worf enjoyed playing the part of Sompek in a holosuite recreation of the battle, always ending the simulation by giving the order to raze the city.202

In 2381 Qo'noS was one of the Alpha Quadrant planets targeted in the Borg attack. The planet was badly damaged in the attack, though not completely devastated.121

Qu'vat117 A Klingon colony world near to the Briar patch. Malik planned to attack the colony with bio weapons in order to provoke a war between Earth and the Klingon Empire, but was prevented from doing so by the NX-01.117 The colony was also the site of a genetic research facility. The Klingons recovered some Augment DNA from the wreckage left after Enterprise destroyed the Augments' ship and used it to develop Klingon Augments. Unfortunately this caused a deadly virus to be created, threatening much of the Klingon Empire.449 The NX-01 travelled to Qu'Vat after the captured Augment Marab provided the co-ordinates.450 The Augments

Risa122 A planet in a binary star system, famed as one of the great vacation spots of the galaxy.332 Risa is the site of the most elaborate climate control system in the Federation, as well as seismic regulators. Without this control a lot of the surface area would have been an unpleasant swampland ridden with earthquakes.122 Risa is approximately 90 light years from Earth, and was first visited by Humans in 2152 when the NX-01 crew took shore leave there. The planet was considered to be very cosmopolitan at the time, with visitors from many different species.460 Tourism was one of the major industries on Risa, with the Vulcan database listing more than two hundred registered Nuvian masseuses on the planet391 and attractions including subterranean gardens filled with luminescent plants, steam pools460, and a water recreation park.461

In 2135 T'Pol tracked a two Vulcan fugitives to Risa. She killed one, but the other escaped.126 In the 24th century, Commander Riker was very fond of the planet and managed to convince Captain Picard to holiday there.122 Riker met and had a brief romance with a Ktarian woman, Etana Jol, on the planet in 2368, though she subsequently proved to be a covert operative.419 Geordi La Forge was on his way to Risa in 2367 when he was abducted by Romulans.372 Starfleet intelligence believed that Federation Ambassador Krajensky was replaced by a Founder infiltrator whilst visiting Risa in 2371208 Worf and Jadzia also vacationed on the planet in 2373, where they encountered the New Essentialist, a small political movement that saw Risa as an example of how decadent the Federation had begun. The New Essentialists briefly seized control of the weather and seismic control systems during the visit.332 In 2375 Grand Nagus Zek and Ishka retired on the planet.179

In 2381 Risa was one of the Alpha Quadrant planets targeted in the Borg attack. Large numbers of Risans and guests were evacuated before the Borg arrived but the surface of the planet itself was devastated in the attack, killing every living thing.121

Romulus458 Located in Sector Z-6, Romulus is the capital world of the Romulan Empire and home planet of the Romulan species.458 Romulus was colonised some time after the rise of Surak's philosophy of non-emotionalism on Vulcan in the year 370. Those Vulcans who refused to accept this transition left the planet, founding various settlements on different planets u as they travelled. One group eventually settled on Romulus and founded a new civilisation there.30 The Romulan civilisation has generally been an aggressive one, and in the 22nd century they fought a war with Earth forces. The war eventually ended with the creation of a neutral zone between the two, a volume of space which both sides were forbidden to send any military forces into.458 Over the years some transgressions did occur, but very few Federation personnel had ever actually penetrated to Romulus itself even by the 24th century.302

Admiral Jarok considered Romulus to be more beautiful than any of the hundred plus worlds he had visited in his military career. He was particularly impressed by the the firefalls of Gath Gal'thong, the Apnex Sea, and the valley of Chula.381

In 2368 Federation intelligence located Ambassador Spock on Romulus34, prompting a covert mission by Captain Picard and Lieutenant Commander Data to the planet. Spock had been working on his own initiative to try and work towards the reunification of the Romulan and Vulcan people. Although Data and Picard did help Spock avert a crisis involving a Romulan attempt to invade Vulcan itself, Spock chose to remain behind on Romulus in order to continue working towards a peaceful reunification.299

The planet Remus was located in the same system as Romulus. In 2379 Shinzon murdered the entire Romulan Senate with Thalaron Radiation and requested talks with the Federation. Captain Jean Luc Picard took the Enterprise-E to Romulus itself, the first time a Federation Starship had penetrated the system. The invitation proved to be a trap, but the Enterprise was able to escape.258

Spock did make some progress in his efforts to deepen relations between Romulus and the Federation and in 2387, when the planet was threatened by an exploding star, the Romulans approached him to request Federation assistance. Spock personally piloted the vessel that would attempt to neutralise the exploding star with an injection of red matter, but he was too late. Romulus was destroyed with the loss of the entire population.287
