• Alpha Quadrant:  That quarter of the Milky Way Galaxy appearing to be located between 6 and 9 o'clock if the great plane of the galaxy is viewed as a clock-face and the 6 o'clock position bisects the Sol system.  The quadrant is home to the bulk of the Federation and the Cardassian Union, along with Bajor and its adjacent wormhole which bridges a 70,000-lightyear shortcut to the Gamma Quadrant.
• Ank:  A faction of the Forlingas sent to Earth in advance of the Lords, who wished to rule the Earth in the stead of the Lords, whom they believed were not coming.

B

• Beta Quadrant:  That quarter of the Milky Way Galaxy located between 3 and 6 o'clock if the great plane of the galaxy is viewed as a clock face and the 6 o'clock position bisects the Sol system. The bulk of the Klingon and Romulan empires, the Ferengi and Tholians are among the major cultures located there along the joint Alpha Quadrant boundary with the Federation, which also extends into it slightly.

D

• DY-100 Class:  An old style interplanetary vessel fitted with cryogenic suspension chambers.

E

• Earth:  Also known as Sol III, or Terra, this is the home world of the Human race, and the center of the United Federation of Planets.
• Enkei:  The leader of the Enu, and sworn enemy of Hefu.
• Enu:  A faction of the Forlingas sent to Earth in advance of the Lords, who wished to remain living in peace with the primitive Human population, existing as Humans in effect.  They came to this decision after it was believed that the Lords would not come to Earth.
• Eugenics Wars:  Wars begun through genetic manipulation of certain Human embryos.  These "supermen", highly intelligent and power hungry, eventually rose to power and lay claim to much of the Earth.  The Eugenics Wars saw them cast down and their armies destroyed.

F

• Forlingas:  An alien race, energy-based, that once lived on Earth and masqueraded as gods.  They eventually became the basis for legends and myths about the classical Greek gods.

G

• Gamma Quadrant:  That quarter of the Milky Way Galaxy appearing to be located between 9 and 12 o'clock if the great plane of the galaxy is viewed as a clock face and the 6 o'clock position bisects the Sol system.  The Gamma Quadrant had been surveyed only remotely until the discovery of the Bajoran wormhole opened it to direct exploration -- and brought on the conflict with the quadrant's major power, the malevolent Dominion and its Founder shapeshifters, Vorta and Jem'Hadar fighters.

H

• Hefu:  The leader of the Ank, and among the last survivors of that faction.
• Human:  The dominant intelligent species native to Earth.  Humans are one of four races that saw the founding of the United Federation of Planets.
• Hur'q:  Klingon term for "outsider," and the term used for a race which conquered and pillaged the Klingon homeworld, Qo'noS. They also apparently knew of the Bajoran wormhole and its uses.

K

• Keats, Jonathon:  The father of Martin Keats, Jonathon was a high profile diplomat to the Middle East, even into the Eugenics Wars.
• Keats, Martin Samuel:  Born in the late 20th Century, Martin would suffer through the Eugenics War with an artificial disease that would see him placed in a cryo-satellite and, eventually, revived in the 24th Century.  He is the current commanding officer of the USS Endymion.
• Klingon:  The well-statured warrior race has a genetic predisposition to hostility and a well-known streak of fatalism. The culture's warrior ethic runs so deep that rivals in the civil war can meet and drink as equal fighters for periods of time before or after battles, thanks to the Capitol City's neutrality. During these get-togethers, a great deal of growling, wrestling, snarling and generally loud revelry takes place, Klingons seeming to derive tremendous satisfaction from drinking with their enemies on the night before a battle. 
  
  A beard is a symbol of courage; a hammer is a symbol of power. A true warrior fights to the death and would rather be killed than taken hostage — an act which brings dishonor on himself and his family for three generations. Their most important historic symbol of leadership, Kahless, said Klingons should fight not just to spill blood but to enrich the spirit. Their scientists are not highly regarded in the culture.
  
  In the traditional sense, the Klingon people hold honor above life — although as with any culture, high-level politics and personal gain get in the way. In Klingon culture, lower-ranked officers consider it a duty to kill off a superior who is perceived as weak. 
  
  Warriors and their families are responsible for each other's actions. A challenge to clear a family's name ends in death if unsuccessful. They believe that death is an experience best shared and view it as a joyful time for one who falls in the line of duty and earns a place among the honored dead, celebrating the release of a dead spirit rather than grieving over what they consider to be the empty shell of the body. One of the most honorable deaths is a kamikaze-like suicide that takes an enemy's life with it. Viewed through their Spartan perspective, illness (especially terminal) is not honorable.
  
  Klingons usually mate for life, celebrated with a solemn Oath of Union, most often in private, rather than in a public ceremony like marriage.  Women cannot sit on the High Council. 
  
  Klingons are remarkably skilled hunters, relying on their keen olfactory senses to pick up and stalk their prey. They eat their meat raw, seasoned more strongly than humans prefer, and find the human tradition of "burning their meat" to be somewhat repulsive.
  
  The custom of naming godparents or other relatives is practiced among Klingons as well as humans.  Despite the disillusionment and disrespect of some Klingons, Klingon honor still counts among the peoples.
  
  Although they believe in an afterlife, Klingons perform no burial ritual and dispose of the corpse by the most efficient means possible — although some archeological digs on Qo'noS revealed different customs at one time.

L

• Lords:  The ruling caste of the Forlingas species.  These individuals eventually became known primarily by their Greek god synonyms.

S

• Sandrine's:  A small bar located in Marseilles, France.  It has been open since at least the late 1700's.
• Singh, Khan Noonien:  One of history's most notorious dictators, Khan Noonien Singh was a genetically-bred human "superman" of Earth's India in the late 20th century who died in the 23rd century amid another "experiment" gone wrong. Rising to power among others of his kind, his ambition helped foment the Eugenics Wars that involved much of Earth's Third World. Finally facing defeat, he and dozens of followers escaped in the S.S. Botany Bay, a DY-100 vessel modified as a sleeper ship which drifted in interstellar space for over two centuries, until it was discovered in 2267 by the U.S.S. Enterprise. With his fellow survivors, Khan attempted to seize that starship but failed, and he and his people were sentenced by Captain Kirk to tame the wild M-Class world of Ceti Alpha V. Among those exiled was Lt. Marla McGivers, an Enterprise historian who fell in love with Khan and initially assisted him; ultimately, though, she refused to betray Kirk and her shipmates in the tyrant's abortive takeover.  On Ceti Alpha V, the band of refugees thought their dream of conquering an entire planet would come true, but six months after being left there, the star system's sixth planet exploded, and the shock wave wreaked havoc on planet V's ecosystem, making it a desert wasteland. In 2285, the embittered Khan commandeered the U.S.S. Reliant and hijacked the top-secret Genesis Device in a plan to exact vengeance against James T. Kirk. Khan failed to defeat his old foe, and died when he detonated the cataclysmic matter-reorganizing terraforming device, annihilating the Reliant.
• Starling, Henry:  In an alternate timeline, Henry Starling captured a damaged 29th-century timeship in 1967 and used its contents to assist in the development of Earth's computer revolution. To that end he founded Chronowerx Corporation, based in Los Angeles. In 1996 Starling attempted to take the timeship back into the future, but died when the ship was destroyed by the U.S.S. Voyager.  In the true time line, Starling may have had some influence in the computer industry, but his role in its development was almost certainly minor.
