New Frontier characters Characters from " " ( Pocket Books , by Peter David ) Regular characters . Mackenzie Calhoun . Captain is the central character of the " New Frontier " series , the commanding officer of the starship . He was born named M ' k ' n ' zy , in the town of Calhoun on the planet Xenex . The Xenexians were slaves of the Danteri race , and young Calhoun saw his father brutally murdered by them in public . After negotiations chaired by intervening Federation mediator Jean - Luc Picard of the starship " Stargazer " failed , M ' k ' n ' zy , still only in his teens , led his people in a fierce uprising , completely defeating the overlords from Danter . Picard likened him to Alexander the Great , conquering his whole world before the age of 20 . After this victory , M ' k ' n ' zy accepted a sponsorship to Starfleet Academy from Picard , adapting his name to the more pronounceable " Mackenzie " and taking the name of his home settlement , Calhoun , as his family name . He is currently commanding officer of the starship USS " Excalibur " NCC - 26517 - A . At the beginning of his Starfleet career , he developed a close personal relationship with fellow officer Elizabeth Shelby , who eventually became his first officer for several years aboard his first command , the starship USS " Excalibur " NCC - 26517 . Calhoun ' s career is not flawless , however : he has a reputation as a hot - blooded maverick , and resigned from Starfleet in anger following a fiasco aboard the , where he was posted as first officer . The " Grissom " s captain died while engaging in a clear and severe violation of the Prime Directive on Calhoun ' s watch . Even though he was cleared of any wrongdoing , Calhoun was angered by Starfleet ' s treatment of the situation , as well as his own , and actually assaulted Admiral Edward Jellico , beginning a long - running antagonism between the two . He spent several years working for Starfleet Intelligence on an as - needed basis as an undercover operative under Admiral Alynna Nechayev before recommendations from Ambassador Spock and Captain Picard placed him back in active duty , in the center chair of the " Ambassador " - class USS " Excalibur " charged with the mission of patrolling the politically unstable area of space formerly controlled by the Thallonian Empire , which fell in 2373 . In 2375 , during this assignment , Calhoun discovered his son , Xyon , fathered in 2354 on Xenex . In 2376 the " Excalibur " was destroyed by a computer virus . Calhoun was believed dead , but survived on the planet Yakaba , where he adopted 11 - year old Moke as his son . He escaped the planet and returned to Starfleet to take command of the new " Galaxy " - class USS " Excalibur " - A . He married Elizabeth Paula Shelby at that time . Elizabeth Shelby . was part of an elite unit assigned to assess weaknesses in the Borg during the Federation ' s early confrontations with that species . She served briefly as first officer of the , under the command of Acting Captain William T . Riker , following the abduction of Captain Jean - Luc Picard by the Borg . After helping rescue Picard , Shelby graciously relinquished her post as " Enterprise " first officer to Riker , who , though he often found Shelby to be frustrating , commended her as a highly skilled officer . Shelby was a tough - as - nails officer who made no secret of her ambitions . She served under the " Excalibur " s previous captain , who was killed fighting the Borg , and was the top candidate to be its next commanding officer , until the post was given to her ex - fiancé , Captain Mackenzie Calhoun . She was less than thrilled when she found out about his new assignment . Shelby was assigned as Calhoun ' s first officer in hopes that she could keep him in line , but she soon established a " modus vivendi " with Calhoun , and served as his first officer with great distinction . After the destruction of the " Ambassador " - class USS " Excalibur " in 2376 , Shelby was promoted to captain of the . She later transferred off the " Exeter " , citing personality differences with her senior staff . She was offered , and accepted , command of the new , " Galaxy " - class " Excalibur " , and reassembled the crew from the prior " Excalibur " . At the christening and launch ceremony for the new starship , Mackenzie Calhoun dramatically interrupted the proceedings to let it be known that reports of his demise were greatly exaggerated , and to propose marriage to Shelby . She accepted , and was married to Captain Mackenzie Calhoun on the bridge of the newly - christened Starship " Excalibur " . Captain Jean - Luc Picard performed the ceremony . Shelby was given command of the USS " Trident " , which was assigned to Sector 221 - G with the new USS " Excalibur " , captained by her husband . She was later promoted to the rank of admiral and given command of Space Station Bravo . Burgoyne 172 . , a Hermat , was something of an anomaly among the Hermat people : extremely outgoing , playful , and prideful whenever s / he managed to solve some sort of problem or difficulty . Burgoyne served as the chief engineer of the USS " Excalibur " under Captain Calhoun until the ship ' s destruction in 2376 . Burgoyne also enjoyed a brief romantic dalliance with Mark McHenry and described their association as a " friendship with fringe benefits . " Burgoyne sired one offspring with Dr . Selar . They named the child Xyon , in honor of the son of Mackenzie Calhoun , who appeared to have been killed defending Tulaan IV from the Black Mass . When Dr . Selar insisted on raising Xyon as a Vulcan citizen , Burgoyne sought legal remedy from the Hermat Directorate , but was refused . S / he was forced to plead the case for parental rights before the Vulcan Judgment Council , in opposition to Selar . The two parents eventually reached a mutually agreeable settlement . Burgoyne was promoted to the rank of commander and assigned to the new USS " Excalibur " - A in 2376 as first officer under Captain Calhoun . Selar . was the chief medical officer on USS " Excalibur " under Calhoun . An accomplished physician who trained under Dr . Beverly Crusher of the , Selar was accused of lacking a good bedside manner . One of the most important moments in Selar ' s life was the death of her mate , Voltak , during the early moments of their " pon farr " joining . This premature disruption of the Vulcan mating ritual resulted in a delayed - reaction mating urge , which forced Selar to resume " pon farr " less than three years after the death of Voltak . Although Selar initially selected Captain Calhoun to act as her mate during her unexpected " pon farr " , she ultimately mated with Burgoyne 172 . She subsequently became pregnant , and named the child Xyon , in honor of Xyon of Calhoun , the ostensibly late son of Captain Mackenzie Calhoun . In " After The Fall " , which is set several years into the future from the previous novel , " Stone and Anvil " , it was discovered that she had become estranged with Burgoyne over their son . Selar was desperately trying to find a cure for Xyon ' s incredible aging rate which left him only a few years to live . Robin Lefler . The operations manager on USS " Excalibur " under Calhoun , , had previously served as a member of the engineering staff of the " Enterprise " - D . She was renowned for her off - the - cuff recitation of " Lefler ' s Laws , " pithy observations and comments that mysteriously seem to suit whatever occasion was presented . Lieutenant Commander Lefler served as Starfleet ' s representative to the New Thallonian Protectorate . She was married to Prime Minister Si Cwan of the Protectorate until his death at the hands of Fhermus , but continued to serve the New Thallonian Protectorate , helping Kallinda lead her people toward the rebuilding of Thallonia . Mark McHenry . The conn officer on USS " Excalibur " under Calhoun , , was a brilliant navigator , capable of performing calculations faster than the ship ' s computer while calculating pi to the fiftieth decimal place . He could also detect the slightest changes in direction of a ship at warp . He had short - cropped red hair , blue eyes , and freckles . He , Zak Kebron , Soleta , Worf , and Tania Tobias all joined Starfleet Academy in 2357 and remained friends for all four years at the Academy . During a confrontation witnessed by Zak Kebron , Q suggested that McHenry was not what he appeared to be , and might be considerably more than just a gifted Human . It turned out that he was , in fact , a direct descendant of Apollo ( who had impregnated Carolyn Palamas ) . In 2376 , he left the USS " Excalibur " in non - corporeal form to guard against his evil , divine relatives . Zak Kebron . The USS " Excalibur " Chief of Security , , was a member of the high - density race called the Brikar , and had to wear a small gravity compensator on his belt at all times . If he did not , his more - than - earth - normal mass made it impossible for him to move . The Brikar were an inorganic race of sentient beings that were silicon - based , appearing to be made of living rock , humanoid in shape but substantially larger in stature than Humans . They were considerably stronger than Humans and were fairly impervious to physical attack due to their rocky composition . As such , Kebron was capable of enduring phaser blasts that would kill a normal humanoid , and he was a skilled player of three - dimensional chess . He underwent dramatic biological changes in 2376 and thereafter combined his duties as security chief with those of ship ' s counselor aboard the USS " Excalibur " . His roommate at Starfleet Academy was Worf . This was despite the fact that there was little love lost between the Brikarians and Klingon s due to an unsuccessful attempt by the Klingons to enslave them . Soleta . was the science officer on USS " Excalibur " . Her previous experience in Thallonian space made her uniquely qualified for service on the " Excalibur " when it was assigned to Thallonian space . Early in her Starfleet career , during a visit to Plexus IV , she was detained for roughly 94 hours for failing , upon her arrival , to stand and listen to the local clergy extol the virtues of the Plexian deities . During her first mission in Thallonian space , she was captured on the planet Thallon while conducting geological research . She was rescued from a Thallonian prison by Spock , who was disguised as a Thallonian . On their way to safety they were intercepted by Thallonian prince Si Cwan – later known as Federation ambassador Si Cwan – who chose to facilitate their escape rather than sound the alarm . Si Cwan later asked Soleta to repay this favor by smuggling him aboard the " Excalibur " . Because her natural father was a Romulan , Soleta had occasional difficulty controlling her emotions . Soleta was raised by her mother , T ' Pas , and adoptive father , Volak . Soleta first confronted Rajari , the Romulan criminal who raped her mother , while she was serving aboard the starship " Aldrin " . Years later , she tracked the terminally ill Rajari to the Titan Colony , following his release from a Federation prison . He duped her into traveling to Romulus on his behalf and triggering an explosion that killed several Romulan leaders and leveled a prominent landmark in the capital city . She retired her commission after her Romulan heritage was discovered by Starfleet and returned to Romulus to start over as a member of the Romulan Empire . She was given the rank of commander and a Warbird tailored toward intelligence and espionage , acting directly under the orders of the Praetor . Soleta ' s loyalty to the Romulan Empire ended following the events of , after a " coup " replaced the former government . Using the Warbird that was given to her , she , along with her tribune , Lucius , offered their ship and their services to the New Thallonian Protectorate that Lefler and Kallinda were working to build . Morgan Primus . was the mother of Starfleet officer Robin Lefler , who was conceived on Morgan ' s first date with Robin ' s father . A near - immortal being , Morgan faked her own death in a shuttle accident off the coast of New Jersey during her daughter Robin ' s teenage years . Morgan turned up alive ten years later as a prisoner of the Momidiums in the Gamma Hydrinae system , traveling under the " nom du voyage " Morgan Primus . She ' d come to Thallonian space with her companion , Tarella Lee , in search of the Prometheans . In 2376 , Morgan " died " but her consciousness remained in the USS " Excalibur " computer . Xyon of Calhoun . was the son of M ' k ' n ' zy and Catrine of Calhoun , born during the Xenexian uprising against the Danteri . He captained the " Lyla " and possessed low - level , instinctual psionic abilities that proved sufficient to fool the Redeemer Overlord into believing Xyon was dead . He later faked his own death during the " Excalibur " s rescue of Tulaan IV from the Black Mass , by slipping away during a crisis using his ship ' s cloak ing device . Xyon returned to Thallonian Space in 2379 to tell Kallinda he was still alive and stop her from marrying Tiraud . When she told him to leave , Xyon kidnapped her , but she was taken from him by the Wanderers of Priatia . He returned to New Thallon , where he was tortured until Robin Lefler rescued him . He was then turned over to his father on the USS " Excalibur " . Moke . The son of Rheela , was an impetuous young boy who idolized Tapinza , to his mother ' s great concern . He encountered the marooned Captain Calhoun in the Yakaban desert , and led him back to Rheela . He was later revealed to be the true source of Rheela ' s weather - affecting talents ; members of their family acted as catalysts for one another , and were powerless when alone . After his mother ' s murder , he was adopted by Captain Mackenzie Calhoun , who returned with the boy to Federation space . Moke ' s real father turned out to be Woden , father of the Gods . Xyon . The half - Vulcan , half - Hermat offspring of Burgoyne 172 and Dr . Selar , was named in honor of Xyon of Calhoun . Although predominantly Vulcan in appearance , Xyon displayed such Hermat traits as early maturation of physical skills and a mode of locomotion that involved traveling on all fours rather than fully upright . Xyon developed very rapidly , reaching a biological age in his twenties after just four years . He graduated Starfleet Academy and became a science officer aboard the USS " Excalibur " . Si Cwan . was formerly a popular prince of a royal family in the Thallonian empire whose family was overthrown . Si Cwan actually was liked by the people ; nonetheless , those around him were hated and reviled , which was one of the reasons that the Thallonian empire crumbled . He vowed that he would make the empire a better place for all its citizens , and not just the royal family once he ascended to the throne – unfortunately , he never got a chance to do so before Thallon was destroyed . Si Cwan and the survivors of the " coup " sought refuge in the Federation . Cwan , however , returned to the Thallonian empire to prove that the family is willing to work with the Federation and " by extension " the people of the Thallonian sector , in order to achieve peace . He stowed away aboard the " Excalibur " with the help of Soleta and was made the ship ' s unofficial ambassador by Calhoun upon his discovery . After a lengthy search , Si Cwan located his missing sister , Kalinda , who had been abducted by Zoran Si Verdin . Later , Si Cwan undertook a new quest to avenge the murder of his mentor , Jereme , who was killed by Nikolas Viola , son of Si Cwan ' s longtime rival , Sientor Olivan . He then became Prime Minister of the New Thallonian Protectorate and married Robin Lefler . However , civil war erupted in Thallonian space , pitting Si Cwan against his former political ally , Fhermus , after Kallinda ( or rather a " Wanderer " impersonating her ) killed Fhermus ' s son on their wedding night , reigniting past grudges and old blood feuds . After confronting his sister and discovering that she was an impostor , Si Cwan attempted to surrender and presented proof to Fermus that other forces were at work trying to play them against each other . Despite this , though , Fermus called his evidence a complete hoax and used Si Cwan ' s moment of vulnerability to kill him . Kalinda Cwan . was a former princess of Thallonia and sister of deposed Thallonian prince Si Cwan , who called her by her nickname , " Kally . " She was abducted by Zoran to the planet Montos where she was surgically altered to appear as a Montosian , and brainwashed into believing her name was Riella and that a Montosian woman named Malia was her mother . Zoran did this so that he could take advantage of Kalinda ' s Summons to locate The Quiet Place . Kalinda escaped Montos with the aid of Xyon of Calhoun , with whom she had a short - lived romantic relationship aboard the USS " Excalibur " . Subsequent to her return from The Quiet Place , Kalinda ' s psychic connection with the recently deceased become much stronger . Kalinda lived shortly on New Thallon with her brother . She was kidnapped from her home , first by Xyon and then by the Wanderers , and replaced with a fake by the latter . Xyon and the crew of the Trident sped directly to her rescue after the destruction of the Warden ship and recovered her safely and without harm . After her brother ' s death , though , she had thoughts of suicide , but after communicating with her brother ' s dead spirit , realized that she still had work to do in the living world . She was the last living blood member of the proud Thallonian royal house and served in her brother ' s former role as the head of state with help from Lefler . Edward Jellico . was the admiral serving over Sector 221 - G . He had a rather hostile relationship with Calhoun , although this relationship softened over the years . It was he who suggested that M ' k ' n ' zy change the pronunciation of his name to the more manageable Mackenzie , and to adopt the name of the town he grew up in – Calhoun – as his last name . Janos . was originally mentioned as being a sentient Mugato , but his species was later described ( in " New Frontier : Stone and Anvil " ) as a mutation of several animal and humanoid species , including Caitian and Mugato . Although he served for a time as a security officer on the " Excalibur " , Janos was last known to reside on the world of Neural , and was no longer an active member of Starfleet . Katerina Mueller . Commander originally served as the XO of the " Excalibur " ( the equivalent of the first officer for the night watch ) , but later became the first officer and eventually captain of the " Trident " . She was of German ancestry and attended Heidelberg University on Earth . She had a fencing scar on her left cheek and was an inch taller than Captain Calhoun . Arex . , an Edosian , originally served on the under Captain Kirk as a security officer ( voiced by James Doohan in ) . The three - armed , three - legged officer was stuck in time until he was later recovered by Starfleet . He last served as the chief of security on the USS " Trident " . M ' Ress . served with Arex on the USS " Enterprise " as a communications officer ( voiced by Majel Barrett in " Star Trek : The Animated Series " ) . Like Arex , she was transported through time almost a century and eventually joined the crew of the " Trident " as a science officer . She had some difficulty adapting to the new time period , which was not helped when she was mind - raped by another member of the crew . However , she adapted well , and served as chief science officer on the " Trident " . M ' Ress was a Caitian and had many cat - like features , including pointed ears , a mane , and a tail . She disliked wearing footwear , finding them confining . Romeo Takahashi . served as the conn officer aboard the USS " Trident " He got his nickname from his famous corned beef hash recipe . He spoke with a distinctive southern drawl that belied his Asian ancestry . According to " " : " Once Burned " , Calhoun met Takahashi for the first time on the during the disastrous mission that resulted in Calhoun resigning from Starfleet .
