Biography

Julian Sejan was born on the human colony of Trialas IV in 2225. He was born in a colony that was founded as a scientific enclave that operated independently from, but on friendly terms with, the Federation. Like the scientific colony on Omicron Theta, several of the colonists would be considered scientific extremists or laughing stocks by the Federation at large. Sejan was raised by a single father who experimented with anti-matter and as a hobby and designed small warp-capable crafts. From the influence of these two interests, Sejan gained an understanding of warp theory at a young age. Periodically, Starfleet would scout the colony for possible recruits, and at the age of 16 Sejan was offered enrollment at the Academy for having an understanding of modern warp technology that already rivaled any standard graduate. He was placed on an accelerated track through many classes at the Academy and quickly satisfied all graduation requirements in the fields of science and engineering. Tactics, philosophy, and other fields of study made up the remaining two years at the Academy. Sejan graduated in 2245 at the age of twenty.

During his time at the Academy, he had been marked by the Daystrom Institute as one of the most promising students in his class and was immediately offered an internship at the Institute upon graduating from the Academy. Within a year, he had learned all the Institute felt he needed to become a full-fledged member of the Institute and its projects. After four years with the Institute, at age 24, Sejan was invited to join the starship design board at San Fransisco Fleet Yards. As war with the Klingons and other threats intensified, Starfleet began to seek more combat-focused starship designs. Sejan led the development of higher-yield warp cores that allowed the mounting of more powerful energy weapons on upcoming classes such as the Predator- and Avenger-class starships. As the years passed and the Federation expanded, the design teams at the Fleet Yards attracted a greater number of experts and new thinkers. In 2259, the diverse enough that it broke into separate teams with specialized focuses, and Sejan became a member of the newly formed Special Propulsions Group.

This Group was called upon in 2260 to help redesign the warp core for the Constitution-class vessel in preparation for deploying one such ship on a five-year exploration mission. Missions of such a length had been undertaken before, but never by so large a ship. Moreover, the Constitution classes had recently been fitted with the new, higher-yield weapons that Sejan’s work had helped enable. The Special Propulsions Group was charged with enhancing the yield and life-span of the Constitution warp core while minimizing the maintenance it would require over five years. The Group was able to meet these goals, which helped the USS Enterprise undertake her famed five-year mission. The energy yield and low maintenance of this design came at the cost of the warp core needing to be completely replaced approximately every five years. As a result, soon after the Enterprise returned from her mission in 2270, it was called in for a significant overhaul and refit. The Special Propulsions Group was again called in to work on the redesign of the Constitution warp core as part of the development of the refit modifications.

After the redesigns for the Constitution-class were complete, Sejan worked on a series of projects with the Group before returning in 2274 to the Daystrom Institute and focus on theoretical physics and improved navigational computer design. While researching at the Daystrom Institute, Sejan was offered a theoretical physics professorship at Starfleet Academy. While there, he encountered Casper Bashir, a student who showed a talent for engineering and astrophysics problems. The two became friends and spent a great deal of time together until Bashir graduated in 2279. Over the next four years, Sejan became involved with a discussion regarding the future of the Starfleet and the strain it was facing under the ever-more-frequent need for repairs and refits to maintain the current fleet. The Federation decided they were going to invest in a new line of ship to replace the aging models, and they called on a wide variety of experts to propose new designs and theories to make this new line of ship the most advanced vessel in the Quadrant. Sejan began connecting with other physicists and engineers who were studying transwarp theory. With a few of his peers, Sejan proposed that the new line of ship take advantage of a theoretical transwarp drive, which would enable nearly instantaneous travel from one point to another. At the time the theory was untested, but Sejan set about creating laboratory models and scale demonstrations. After these proved successful, Sejan was given permission to lead the construction of a full scale transwarp drive for the prototype vessel now known as the USS Excelsior.

Production of the so-called “Great Experiment” was rushed to meet the planned 2285 debut. The extraordinary claims made about the transwarp drive quickly became the centerpiece of the Excelsior project, and Sejan’s team was given effectively unlimited resources. Sejan pulled in the better part of the Theoretical Propulsions Group, as well as Casper Bashir, to work on the project. Ultimately, Sejan’s team designed the most powerful warp drive Starfleet had ever seen, and a ship capable of entering transwarp space, but the transwarp drive itself proved to be a failure. Sejan’s team was commended for their efforts, but they were swept out of the limelight. Even if they were hailed as brilliant engineers for helping to produce the most powerful ship in Starfleet, they were remembered privately as professional failures for delivering a transwarp drive that could not live up to the wild claims that had been made about it.

After the crew of the Excelsior had a falling out with Montgomery Scott, Sejan was offer the position of chief engineer aboard the Excelsior, which he accepted, serving from 2285 through 2289. After he retired from active duty aboard the Excelsior, he returned to his teaching position at the Daystrom Institute. Four years later, Sejan reunited with Bashir at the christening ceremonies for the USS Enterprise B. Following this meeting, the two conceived a redesign of transwarp drive, under the title of the Hyperion Project. Over the next six years, the two led the construction of the USS Hyperion at the newly opened Utopia Planitia Fleet Yards while they both taught at Starfleet Academy while they combed through the pool of cadets to find possible future crew members for the Hyperion.

The Hyperion launched in May 2299, successfully (if unofficially) demonstrating the transwarp drive in an unauthorized jump to the Bajoran system of Velos, in an effort to save that colony from the fate that befell Koralis III. Soon after this unauthorized jump, the Hyperion returned to Earth to formally demonstrate the transwarp drive. The demonstration was attended by representatives from many scientific and engineering organization from across the Federation. The demonstration involved three transwarp jumps that would take the Hyperion from Earth to the Galactic Core in the span of about 10 hours. Upon reaching the Core, the Hyperion crew and the visiting observers conducted brief studies of phenomena inside the Core, such as the paradox of youth. This anomaly was discovered to have been caused by an anti-time eruption. A mishap involving a warp-capable probe triggered a space-time tear near this eruption, and the Hyperion was forced to make a transwarp jump in order to escape. This jump hurtled the ship through many possible realities before it ended up in the so-called Mirror Universe and 25 years in the future from when they left.

Death

“Here lies Phaethon, his father’s charioteer; great was his fall, yet greatly did he dare.” – Casper Bashir, quoting Ovid’s Metamorphosis

An unprecedented burst of electro-static plasma flooded through the ship during this catastrophe, threatening to destroy the Hyperion. Sejan decided that the only option was to reverse the flow of this plasma back to main engineering. From there, the emergency ventilation systems in main engineering could vent the plasma. This meant manually managing this ventilation system, and venting the plasma into the main floor of the engineering deck. Sejan and sixteen engineers died carrying out this plan, but the Hyperion was saved.

Two days later, a funeral was held in the Hyperion’s aft cargo bay, with Bashir providing a brief eulogy. After the ceremony, Bashir officially stepped down as acting captain to take Sejan’s place as chief engineer.
