"Catspaw" Stardate 3018.2 The U.S.S. Enterprise explores planet Pyris VII, making first contact with entities of unknown origin. These aliens are found to possess technology permitting the transmutation of matter.

The Enterprise is assigned to treat Assistant Federation Commissioner Nancy Hedford for Sakuro's disease. An Enterprise shuttlecraft is dispatched to pick up Commissioner Hedford from Epsilon Canaris III for transport to the ship. Hedford had been assigned to Epsilon Canaris III to prevent a war.

"Metamorphosis" Stardate 3219.8 The Shuttlecraft Galileo, carrying Kirk, Spock, McCoy and Commissioner Hedford, loses control and makes an emergency landing on a planetoid in the Gamma Canaris region. The shuttlecraft is successfully recovered, along with the missing Enterprise personnel, but the terminally ill Commissioner Hedford chooses to remain behind and is presumed to have died.

"Friday's Child" Stardate 3497.2 The U.S.S. Enterprise is assigned to negotiate a mining treaty with inhabitants of planet Capella IV. Also bidding for rights is a Klingon agent. Negotiations are complicated by local power struggle, resulting in selection of a new leader, whose regent agrees to a treaty with the Federation. The new leader, an infant chosen according to Capellan Law, is named Leonard James Akaar, in recognition of the assistance of Leonard McCoy and James Kirk in maintaining Capellan independence.

"Who Morns for Adonais?" Stardate 3468.1 The Enterprise, collecting data on planets in the Beta Geminorum system, discovers a previously unknown life-form near planet Pollux IV. This life-form, identifing itself as Apollo, was apparently the last of a group of entities that resided on ancient Earth, and claimed to be the basis of the Greeks' myths of the gods.

Spock, under the influence of pon farr, the Vulcan mating drive, ceases eating and becomes severely withdrawn. Dr. McCoy later examines Spock and expresses the opinion that Spock must return to his home world within a week or die.

"Amok Time" Stardate 3372.7 The U.S.S. Enterprise is on a diplomatic mission to planet Altair VI. Kirk, acting against Starfleet orders, diverts the ship instead to planet Vulcan so that Science Officer Spock may return to his native world to fulfill the normal Vulcan seven-year mating cycle.

On Vulcan, T'Pring, Spock's betrothed, demands a Koon-ut-kal-if-fee challenge for the right of marriage. T'Pring later chooses instead to marry Stonn, thus freeing Spock.

The U.S.S. Enterprise proceeds to Atair VI on its diplomatic mission, albeit a bit late. The mission entails participation in a presidential inauguration ceremony, expected to stabilize the entire Altair system after a long interplanetary conflict.

Stardate 4202.1 The Starship Constellation, under the command of Commodore Matt Decker, encounters several destroyed solar systems, presumably including system L-370. Science officer Masada reports that the fourth planet of system L-374 seems to be breaking up, but heavy subspace interference prevents notification of Starfleet Command.

The Starship Constellation is nearly destroyed by an automated weapon of unknown origin. In an effort to save his crew, Commodore Matt Decker transports the ships's company to the third planet of system L-374, but all are subsequently killed when the robot weapon destroys that world as well.

"The Doomsday Machine" The U.S.S. Enterprise, responding to a distress call from Starship Constellation, discovers wide-spread destruction in solar system L-370, L-374, and other systems in the sector. The Constellation is discovered to be derelict, apparently attacked by an immensely powerful force. Commodore Matt Decker, in command of the Constellation, is found to be the sole surviving crew member. Decker reports his findings on the nature of the automated planet killer, theorizing that it is of ancient extragalactic origin. Tactical projections suggest that if unchecked, this device will pass through the most densely populated portion of the galaxy near the Rigel colonies. In an effort to prevent this, Decker pilots a shuttlecraft on a suicide mission into the "doomsday machine." Decker is unsuccessful, but data from his attempt are used to conduct a second effort, using the more powerful reactors from the derelict Constellation. The second attempt is successful, resulting in the destruction of the Constellation and the deactivation of the planet-killer.

Engineering officer Montgomery Scott is injured in an explosion aboard the U.S.S. Enterprise.

"Wolf in the Fold" Stardate 3614.9 Engineering officer Scott, on therapeutic shore leave on planet arglius II is accused of the brutal murder of a native woman. Inquiry by local authorities supports the accusation, and diplomatic relationships between Argelius and the Federation are strained by two additional murders for which Scott is also accused. Further investigation reveals the presence of a previously undiscovered energy entity which feeds on the emotion fear in humanoids. It is further discovered that this life-form was the actual cause of the murders, as well as numerous other previously unsolved crimes.

The four planets of the Malurian system are attacked by an unknown agency. More than four billion people are wiped out, including members of a Federation science team led by Dr. Manway.

"The Changeling" Stardate 3451.9 The U.S.S. Enterprise investigates the recent unexplained attack on the Malurian system, and discovers the cause of the destruction to be an ancient space probe. The probe, known as Nomad, had been launched from Earth in the early 21st century on a mission to search for extraterrestrial life. It is determined that a freak accident involving an alien space probe called Tan Ru caused Nomad to execute a mission of "sterilizing" all life-forms. It is believed that Tan Ru had been programmed to sterilize soil samples, possibly as a prelude to colonization, and that the control programs of the two probes had somehow merged in the collision. Kirk succeeds in destroying the errant Nomad with a minimum of further destruction.

Planet Ceti Alpha VI explodes, disrupting the orbit of Ceti Alpha V. The resulting climatic changes are devastating to the colony there, headed by Kahn Noonien Singh. Starfleet remains unaware of the explosion and of its consequences until 2285, when the Starship Reliant investigates the planet as a possible site for Project Genesis testing.

"The Apple" Stardate 3715.3 The Enterprise conducts a routine survey of planet Gamma Trianguli VI. Survey party reports discovery of a primitive humanoid culturer, but further investigation yields evidence of an immensely powerful and ancient computer system that controls the planet's climate. It is determined that the computer, known to the planet's inhabitants as Vaal, has become the central object of the planet's religion, as the native civilization apparrently exists primarily to provide fuel for the computer system. Upon detection of Enterprise personnel on the planet, Vaal attempts to discourage the investigation by causing the death of two Enterprise crew members and attempting to destroy the starship in orbit. Arguing that Vaal has served to stagnate the planet's culture, Kirk orders ship's phasers to destroy the computer, thus permitting the inhabitants of Gamma Trianguli VI to return to a normal course of cultural development.

"Mirror, Mirror" The Enterprise is on a diplomatic mission to the Halkan system to secure dilithium mining rights. The assignment is impended by a severe ion storm that nearly results in the loss of the Enterprise landing party due to the storm's disruption of transporter functions. It is learned later that transport disruption rersulted in exchange of landing party members with corrrresponding individuals from a parallel dimension, and both parties are returned to their original dimensions.

Upon their return, landing party members report the alternate universe to be remarkably similar to their own, but much more violent, controlled by a repressive empire. They also report that the alternate Spock, understanding the inevitability of change and the accomanying potential for loss of life, may be willing to help guide his society in a more humane direction.

Starfleet loses contact with Federation cultural observer John Gill, stationed on planet Ekos.

U.S.S. Enterprise assigned to transport Commodore Stocker to Starbase 10.

"The Deadly Years" Stardate 3478.2 U.S.S. Enterprise on resupply mission to Gamma Hydra IV research colony. Landing party reports all colonists dead or dying, victims of an unusual hyperaccelerated aging disease. Shortly thereafter, nearly all landing party personnel are discovered to have similar symptoms. Commodore Stocker orders the Enterprise on a direct course to Starbase 10 so that the starbase's medical facilities can be employed to help curer the hyper aging disease. The course takes the Enterprise across the Romulan Neutral Zone, resulting in a confrontation with a Romulan spacecraft. Medical Officer McCoy develops a cure for the disease, based on old adrenaline-based therapies for radiation exposure.

Crew member Norman, recently assigned to duty aboard the U.S.S. Enterprise, evades several attempts by Dr. McCoy to schedule a routine physical examination.

"I, Mudd" Stardate 4513.3 The U.S.S. Enterprise is hijacked by an android masquerading as Enterprise crew member Norman, who takes the ship to a previously class-K planetoid. The perpetrator of the hijacking is discovered to be known criminal Harcort Fenton Mudd. The android population of the planet, which attempts to assume control of both Mudd and the Enterprise, is disabled by Kirk and his staff. It is learned that the androids were originally from the Andromeda galaxy and had been stranded when their home sun went nova. Mudd is released into custody of the android population.

The U.S.S. Enterprise is summoned to Deep Space Station K-7 by a Priority-1 distress call, indicating near or total disaster. Accordingly, the entire quandrant is placed on defense alert.

"The Trouble with Tribbles" Stardate 4523.3 The Enterprise, at Deep Space Station K-7, determines Priority 1 distress call was initiated to protect agricultural supplies of quadrotriticale, a special hybrid wheat deemed stragetically essential to the development of Sherman's planet. The planet had been claimed by both the Federation and the Klingon Empire. The concern for security is proven justified when a Klingon operative attempts to sabotage the Federation development claim by poisoning supplies of quadrotriticale. The sabotage is accidently discovered when some pet tribbles are learned to have been poisoned by the tainted grain.

"Bread and Circuses" Stardate 4040.7 The Enterprise discovers wreckage of space vehicle Beagle on planet 892-IV, reported missing in the area some six years ago. Enterprise landing party, investigating the wreckage, is captured by the planet's inhabitants. Engineering Officer Scott is successful in resucing the landing party without violating Prime Directive protection of indigenous life-forms by causing a brief failure of local power utilities.

Postmission analysis suggest a variation of Earth's Christian religion may be evolving on planet 892-IV, potentially reforming the planet's Roman culture into a morer humane form.

The Starship Enterprise picks up 114 Federation dignitaries, including 32 ambassadors, for transport to a conference on the neutral planetoid Babe.

Ambassador Sarek of Vulcan suffers a mild heart attack, his second. Benjasidrine medication is prescribed for the condition.

"Journey to Babel" Stardate 3842.3 The U.S.S. Enterprise is en route to planetoid Babel, providing transport of dignataries for talks to consider the question of planet Coridan's admission to the Federation. The conference is disrupted by apparent Andorian terrorism, later discovered to be the work of the Orion government, which opposes Coridan's admission.

Ambassador Sarek suffers another heart attack, and is treated by Dr. Leonard McCoy using blood donated by Commander Spock. The operation is a success, although Sarek's wife, Amanda, opposes the procedure on the grounds of risks to both patients. This is McCoy's first actual surgical experience with a Vulcan patient.

Coridan is admitted to the Federation.

"A Private Little War" Stardate 4211.4 An Enterprise landing party conducts botanical study of a technologically unsophisticated Class-M planet, but becomes embroiled in a local dispute. Spock is seriously injured in this dispute, exposing evidence that the indigenous population has been provided access to relatively advanced weaponry. Further investigation reveals Klingon operatives to be responsible for this cultural contamination. Captain Kirk, who had surveyed the planet some 13 years ago, determines measured provision of similar weaponry to all local groups to be the only means of maintaining survival of all.

The U.S.S. Enterprise is assigned to perform a routine check of the automated communications and astrogation facilities on planetoid Gamma II

The Romulan, Klingon, and Federation governments, in a joint venture, establish a colony on planet Nimbus III, dubbing it the Planet of Galactic Peace. The experiment is a failure, although the colony survives for at least 20 years.

2268

"The Gamesters of Triskelion" Stardate 3211.7 The U.S.S. Enterprise at planet Gamma II for routine inspection of automatic communications and astrogation equipment. During beam-down , landing party personnel are abducted by a previously unknown, technically advanced civilization of planet Triskelion in the M24 Alpha system Captain Kirk learns the inhabitants of Triskelion practice a form of slavery, using captured beings known as "Thralls" as expendable participants in athletic competition. Faced with an untenable situation, Kirk successfully gambles and wins freedom for both the Enterprise crew and the Thralls.

Starfleet Command recieves a message from the U.S.S. Horizon, lost a century ago. The message, sent via conventional radio, suggests the ship had caused cultural contamination at planet Sigma Iota II.

"Obsession" Stardate 3619.2 The U.S.S. Enterprise encounters a cloud creature believed responsible for deaths aboard the Starship Farragut eleven years ago. The creature kills two Enterprise crew members. Kirk pursues the creature back to it's home planet, Tycho IV, where it is killed by a small antimatter charge.

The U.S.S. Enterprise proceeds to rendezvous with U.S.S. Yorktown for transfer of vaccines, which the Enterprise then transports to the colony on planet Theta VII, where they arre urgently needed.

"The Immunity Syndrome" Stardate 4307.1 U.S.S. Enterprise on course to Starbase 6 for R&R, recieves orders to divert course for priority rescue mission to Gamma 7A system. En route, it is learned that the Starship Intrepid has been destroyed, and that the same agency has apparently attacked the Gamma 7A system, killing billions of people there. Investigation reveals the destruction to have been caused by a vast spaceborne organism that creates negative particles and consumes energy from planetary systems and space vehicles. Although nonsentient, the creature is deemed a serious threat to the galaxy and is destroyed.

The crew of the U.S.S. Intrepid had been entirely composed of individuals native to the planet Vulcan.

"A Piece of the Action" The U.S.S. Enterprise makes a follow-up visit to Sigma Iota II (previously visited a century ago by the Starship Horizon), and discovers severe cultural contamination caused by a single book left behind by the previous expedition. In an effort to minimize further cultural damage, Kirk assists local leaders in unifying the planet under a common government.

"By Any Other Name" Stardate 4657.5 The U.S.S. Enterprise answers a distress call, and a landing party is captured by aliens later learned to be advance agents for the Kelvin Empire in the Andromeda galaxy. It is learned that the Kelvan hope to establish a colony in this galaxy and that they believe invasion is the only means by which this can be accomplished.

Captain Kirk negotiates an agreement with the Kelvans whereby a suitable planet can be peaceable set aside for their use. A messager drone is sent to the Kelvan Empire to inform them of the agreement.

A Federation research station is established on planet Minara II to study a nearby star predicted to go nova in about six months. Among the station personnel are Drs. Linke and Ozaba. The star had exhibited signs of imminent collapse for some time.

"Return to Tomorrow" Stardate 4768.3 The Starship Enterprise, venturing light-years beyond explored territory, uncovers evidence of a catastrophic war a half million years ago on a previously uncharted planet. Further investigation results in discovery of canisters containing the intellects of three surviving members of the now-dead civilization. An attempt is made to provide these survivors with android bodies, but one survivor, Henoch, is destroyed when he tries to steal a living body. The remaining two survivors, Sargon and Thalassa, choose to "depart into oblivion."

"Patterns of Force" The U.S.S. Enterprise investigates apparent disappearance of cultural observer John Gill, stationed on planet Ekos. During orbital approach the ship is attacked by a thermonuclear weapon, the first of several discoveries that suggest severe cultural contamination. Investigation reveals that Gill, acting in violation of the Prime Directive, had engaged in a cultural experiment attempting to eliminate the planet's dangerous anarchy by imposing a government modeled after old Earth's Nazi Germany. Unfortunately, in imposing the efficiency of the Nazis, Gill created an enviroment in which the abuse of power also flourished. Kirk assists local inhabitants in overthrowing the Nazi government.

"The Ultimate Computer" Stardate 4729.4 The U.S.S. Enterprise is assigned to perform field testing of the experimental M-5 multitronic computer designed by Dr. Richard Daystrom. Although initial exercises are very promising, later tests in simulated combat reveal the M-5 to be unpredictable, resulting in the destruction of the Starship Excalibur and it's crew.

Enterprise captain Kirk and task force commander Commodore Wesley aboard the U.S.S. Lexington are credited with quick thinking, allowing disconnection of the M-5 unit before further deaths can result. Postmission analysis suggests that despite the M-5's design goal of rendering human participation unnecessary in space exploration, it was human thinking that saved the situation.

"The Omega Glory"The U.S.S. Enterprise discovers the Starship Exeter floating derelict in orbit at planet Omega IV, all crew personnel dead. The boarding party discovers the deaths to have been caused by exposure to an alien biologic agent, apparently brought to the ship from the planet surface. Evidence suggests the planet also contains biologic agents that provide immunity to the disease, so Enterprise boarding party personnel are transported to the surface.

Investigation on the surface of Omega IV suggests that both the disease and the population's immunity are results of ancient bacteriologic warfare, perhaps over a millenium ago. Also discovered is Exeter captain Ronald Tracey, who survived the disease by chance because he had remained on the surface of the planet. Tracey is found to have interfered with the local government, in violation of the Prime Directive, and is taken into custody.

"Assignment: Earth" The U.S.S. Enterprise, on historical research mission into Earth's past, encounters evidence that Earth had extraterrestrial assistance in surviving its critical nuclear age, circa 1968.
