Sela

Sela is the half-Human/half-Romulan daughter of Romulan General Volskiar and his consort, Lieutenant Tasha Yar (a future version from an alternate timeline).

Early Life
Sela was born on Romulus in the year 2345 and grew up in her father's private compound on Romulus's surface. In 2349, when she was four years old, her mother tried to sneak her out of the compound and back to Federation space. Sela, not wanting to be separated from her beloved father and the only life she ever knew, cried out for the guards who captured Tasha, who was then executed in front of Sela. This led Sela to believe that her humanity was a weakness that would be her downfall and stood by this belief all her life. 

Career
By the late 24th century, she had enlisted in the Romulan Star Empire's military forces. While in training, she befriended one of the instructors, Saket, who became her mentor and taught her what it took to become a competent soldier, a good leader, and an expert tactician. It is presumed because of her dominant human features that she suffered racial insults while in training but was able to get through the difficult times with brute force, leading her to adopt a cold and angry attitude to everything. 

Encounters with the Federation
She reached the rank of commander by 2367 and was influential in the Senate and military councils. Given a high-profile mission to destroy the Klingon Empire by any means necessary, Sela initially tried to have an influential Klingon governor who was hostile to the Federation named Vagh assassinated. This would have inevitably led to war as it would confirm Vagh's anti-Federation opinions, especially if the influential Klingon Ambassador Kell (a Romulan collaborator) vouched for him in his memory. To this end, she intercepted the shuttlecraft commanded by Lieutenant Commander Geordi La Forge and brainwashed him to become Kell's unwilling assassin. Unfortunately, the plan failed when Lieutenant Commander Data realized the plot and warned Vagh in time to stop Geordi. While Vagh was saved (and now convinced of the Federation's good intentions), Kell was arrested and later executed.

Shortly thereafter, Sela then sought to use the Klingons' own political instability to her advantage in the wake of the deaths of K'mpec and Duras, son of Ja'rod. Aided by the surviving members of the House of Duras, Lursa, B'Etor and Toral (Duras's illegitimate son), she plotted to unleash a civil war that would consume the Empire and leave the Federation's position weakened without Klingon military support. Using Toral as their puppet, Lursa and B'Etor challenged Gowron's claim to the chancellorship, since women could not serve on the High Council according to Klingon law. Although the Arbiter of Succession, Jean-Luc Picard, ruled that Toral's claim was invalid, the Duras family's influence was still powerful enough to convince almost half of the Council to rally behind their banner. The conflict quickly spread throughout Klingon space, with ships loyal to the Duras family winning almost every engagement. However, the Federation, convinced by Picard that the Duras forces were receiving outside support, sent a fleet to blockade the Klingon-Romulan border and choke off the supply chain. The civil war ended in favor of Federation-supportive forces under Gowron, effectively destroying any remaining influence the Duras family had in Klingon politics and turning Lursa and B'Etor into wanted renegades. 

With the failure of her latest mission, Sela conspired with Proconsul Neral and Senator Pardek to invade Vulcan. She arranged with multiple criminals (such as Omag) to steal three Vulcan transports and use them to ferry 2000 Romulan troops to Vulcan (all of them on loan from the Senate). Thwarted by Picard, Data, and Romulan dissidents led by Ambassador Spock, she was forced to cover up any Romulan involvement in the attempted invasion, ordering a warbird to destroy the transports before the troops could be interrogated by the crew of the USS Enterprise (NCC-1701-D). 

Fall from Grace
The failure to sway the events of the Klingon civil war to an outcome favorable to the Star Empire and the ill-fated attempt to conquer Vulcan resulted in Sela falling out of favor with the Senate, and a corresponding loss of influence among her fellow officers. Matters were made worse when she was reassigned as commander of the IRW N'ventnar, an old, B-Type warbird that she regarded as something of an embarrassment.

Offered a chance to redeem herself in the eyes of her people, a few years later Sela accepted a mission to recruit the Elohsians into the Empire. Seeing that the Elohsians' homeworld was located on the border of the Neutral Zone, she felt that the planet would make an ideal staging area for spying on Federation territory. The assignment went even better than she could have hoped for. With the Elohsians formally becoming part of the Empire, she humiliated Picard in public and exposed the ineptness of the Tal Shiar, leading to the agency's many enemies to rally around Sela and pledge their allegiance to her. Upon her return to Romulus, Sela found herself in a far better position than ever before, with far more influence and power than she had wielded prior to her initial encounter with Picard and his crew. 

In 2371, Sela commanded a task force of warbirds into Cardassian space to recover a sample of a lethal virus created by the Redeemers, which was held by her old ally Saket (now imprisoned by the Cardassians in a labor camp on Lazon II), and use it to launch a secret biological attack on the Klingon homeworld of Qo'noS. Leading the assault personally, she destroyed much of the camp's defenses in a stolen Federation Peregrine-class fighter before abandoning it and beaming down to the surface. Finding Saket with a new friend, ex-Maquis member Thomas Riker, she took them both with her in the escape, although for most of the time Sela believed that Thomas was in fact, Will Riker. Saket, however, had been injured by one of the camp guards in the escape and died in sickbay, however the mission was a success as the sample was found hidden in an eyeball which Saket had replaced with a false one.

Later, Sela and Riker became lovers, with Sela recruiting him in her plans by tasking him to release the virus. Hiding it in a bottle of Romulan ale,the plan was to release the the virus into the atmosphere when the bottle was opened, and to also assassinate Chancellor Gowron. To ensure his cooperation, Sela double-crossed Riker, kidnapping Deanna Troi and Alexander Rozhenko from Betazed and holding them hostage on Lintar IV. Unable to bear the thought of anything happening to Troi, he agreed to her demands. However, the attack was foiled when Deep Space 9's security chief, Odo, replaced the bottle with the virus, tipping off Commander Elizabeth Shelby on the USS Excalibur about the hostages' location. With the hostages rescued safely, Riker fled from Starfleet yet again as Sela and her forces retreated. 

After yet another failed attempt to destabilize the Klingon Empire, by 2373 Sela had become an outcast, fleeing underground. While piloting a one-man shuttlecraft over a remote planet, Sela was shot down by its ninja-like inhabitants, the Bodai Shin. Her old nemesis, Picard, was also stranded and they were forced to work together to escape alive. They soon parted ways after this. 

Somehow regaining her command by late 2375, she led several warbirds to Sector 221-G and attacked the USS Independence (NCC-41452). The ship was quickly destroyed by the warbirds, but many of the crew escaped via escape pods. Sela ordered the escape pods destroyed, and many were, before the USS Excalibur arrived and drove her ships away. 


 * When Sela was last seen in Double or Nothing she was in Starfleet custody and comatose. No explanation was given for her subsequent appearances in Armada and Death in Winter.

In 2376, Sela's new allies arranged to have her promoted to admiral, which led to high-profile projects and command of newer, more capable vessels. At the request of Jal Par, an agent of the Tal Shiar, she was sent with a fleet to capture a recently discovered Omega molecule from the Ferengi and Cardassians and deliver it to a secret research facility. The raid was a success, (through a combination of Ferengi greed for dilithium and the Cardassians' weakened military) and Sela's fleet destroyed countless Klingon patrol ships and invading Borg cubes before escaping through a wormhole to the facility, ensuring the safe delivery of the cargo. Contacting the Borg, she manipulated their belief in the molecule being "perfection itself", further manipulating the Borg into eliminating another threat to the Romulan Empire by destroying Toral's faction in the new Klingon Civil War in exchange for the molecule. After the Borg finished destroying his bases and ships (killing Toral as well), the weakened Borg were then double-crossed and destroyed by Sela, temporarily ending the Borg threat to the Romulan Empire (unfortunately the molecule was later captured by the Borg after they learned where it was being kept by the now-assimilated Jal Par). Sela then served as the Romulan Empire's representative during the negotiations to form the Alliance against the Borg invasion. 

After Shinzon
In 2379, during the power vacuum created by the demise of Praetor Shinzon (whose coup d'état served to cripple the Empire and resulted in the deaths of the entire Romulan Senate), Sela became a personal agent of the new Praetor; Tal'Aura, though she had to accept a demotion back to Commander.

In the days following Shinzon's coup, the Romulan Empire faced a myriad of challenges, the most unexpected of which originated from their farthest outer subject worlds. These worlds were critical components of the Empire's economy, and their native populations had long been dissatisfied with their treatment under Romulan rule, making minor attempts at rebellion and secession over the years. After the coup, the natives began taking their objections to the streets and openly challenging Imperial authority. Soon, their continued submission to Romulus was in jeopardy, and Tal'Aura had a growing list of rebellions to deal with.

As a result, Sela (whom Tal'Aura referred to as "the half-blood"), her best operative, was sent to the frozen planet of Kevratas, which was located on the fringe of Romulan territory and possessing the strongest area of rebellion activity. Due to her own experiences, however, Tal'Aura also sent a second operative and veteran spy, Manathas, to Kevratas without Sela's knowledge. Nevertheless, Tal'Aura was confident that Sela would succeed in her mission against the "crude" rebels, since Sela had performed many such errands in the name of the Praetor's predecessors, gaining a reputation for her cold and ruthless efficency.

Somehow, Sela received word that a Federation scientist, Doctor Beverly Crusher, was meeting with the rebels on Kevratas. Knowing of Crusher's longtime affiliation with Picard and seeing an opportunity to avenge her past defeats at the hands of Picard and his crew, she personally led a squad of soldiers that successfully trapped and captured Crusher, faking her death in the process. However, Picard did not accept this, and mounted a rescue with the aid of his old shipmates Pug Joseph and Doctor Carter Greyhorse. Following the incident, Tal'Aura ordered Sela to remain on Kevratas for the time being, monitoring the tenuous situation along the empire's border worlds. 

In 2383, she served as Chairman of the Tal Shiar under the administration of Praetor Kamemor. 

In 2384 after word got out about Sela's involvement in the plot to obtain slipstream technology from the Federation - a plot which led to the destruction of Deep Space 9 - she was placed under arrest by Praetor Kamemor. Sela then committed suicide in her cell. 

Online timeline
Accused of attempting to assassinate the head of the Tal Shiar in 2386, Sela was found guilty of treason by the Senate, although no evidence was brought forward at her subsequent trial. As Sela faced execution, Donatra, her main political rival, intervened in the matter on Sela's behalf. Despite being unsuccessful at dropping the charges, Donatra convinced the Senate to reduce Sela's sentence from that of execution to one of exile. Quietly accepting her last-minute reprieve, Sela took a small fleet of ships and set a course for the Delta Quadrant. During the Hobus supernova event a year later, Klingon long-range sensors detected her fleet passing the Beta Stromgrem supernova remnant, continuing into unexplored space.

In 2391, a Federation operative within Sela's fleet reported they had settled on a planet within the Beta Quadrant and had begun mining resources.

Five years later in 2396, operatives reported trading with ships similar to those seen by the USS Voyager when they were lost in the Delta Quadrant. 

25th century
The Empire was devastated for many years, however by 2408, the Romulans had established a new homeworld on Nova Roma and had reinstated the Romulan monarchy with Sela as the new Romulan Empress. 

Appearance and personality
Sela is described as bearing an uncanny resemblance to her mother; inheriting her "piercing gaze, (her) strong but feminine features, close-cropped blond hair, and the determined jut of her chin". The only exception is her pointed Romulan ears. This is considered an ironic twist; as she is entirely her father's daughter under the surface. Despite the setbacks she faced, Sela proved to be one of the craftiest and most dangerous individuals certain Federation personnel (e.g. Jean-Luc Picard, Beverly Crusher etc.) had ever encountered.
