Grigor Daan Eisenberg-Sloane was the sixth of seven children born to Marius and Natasha Eisenberg-Sloane, the third born during their residence in Bremen, Germany. Marius served as pastor for the Holy Trinity Church of the Third Reformation and Natasha remained at home with the children, doing occasional work as a holonovelist.
As a child, Grigor’s parents encouraged him to learn, explore, and carefully examine the information and decisions put before him in addition to instructing him in matters of faith and religion. For young Grigor, this combination of faith and reason came to a tragic test when his brother Walter died unexpectedly while interning at a hospital in Spain during the fall of 2369. This loss impressed two lessons in the boy’s mind: the fragility of life, and that tragedy and loss will happen even in the best prepared environments.
In 2371, Marius was asked to step into the role of bishop for part of the Berlin region and the family moved to a town near the city. Having had an interest in military history since childhood and wanting to do something for the defense of Earth in the wake of the Dominion War, when a Starfleet recruiter visited the school, Grigor was one of the first to sign up for the entrance exam. His parents were reserved but accepting of his decision.
The first few days at the Academy were difficult ones for Grigor. Having lived predominantly in suburban areas for the vast majority of his life, there had been very few opportunities for direct interaction with alien species. This led to several altercations with more aggressively-minded individuals. Academically Grigor did as he had always done in school: quite well, qualifying for a spot on a Nova trainer during his senior year. Graduating in the top fifteen percent of his class with a major in military history, Grigor was commissioned as an ensign and assigned to the Excalibur-class USS EISENSTEIN as a member of the Tactical staff.
Over the next two years Grigor distinguished himself in the department, displaying a knack for exploiting subtle weaknesses and developing a reputation for exacting precision. Investigating mysterious energy readings from a previously uncharted system, the EISENSTEIN found itself caught in the middle of war between two of the worlds. Following an unsuccessful attempt to broker a peace accord between the two sides, the EISENSTEIN withdrew from the system after heavy damage.
Eight months later the EISENSTEIN was attached to a task force combating an increase in piracy near Orion space. Over the next three months the task force was successfully able to reduce piracy rates to below previous levels and when the EISENSTEIN was redeployed, Grigor was offered a transfer to the Akira-class USS RASSILON in 2382 as a replacement for one of the ship’s recently departed Tactical Officers. He accepted the position and remained with the RASSILON, putting the skills learned in the EISENSTEIN’s to good use during the RASSILON’s continued patrol near Orion space.
During a raid on an Orion slave processing station in early 2384, the RASSILON’s patrol group came under heavy fire from a fleet of Orion and Naussican vessels that had been lying in wait nearby. During the ensuing battle the RASSILON’s Chief Tactical Officer was killed. Taking over, Grigor was able to coordinate with the rest of the patrol group to hold off the pirate fleet long enough for away teams to be recovered and an escape made, disabling half a dozen pirate vessel in the process through the use of “unorthodox weapon solutions.” Upon return to spacedock, Grigor was assigned to the position of Assistant Chief Tactical Officer.
In mid-2486 the RASSILON was reassigned to track down and arrest Kej Tal, an Orion pirate and mercenary who had begun to form a new cartel within Federation space. By the end of the year, the RASSILON’s crew had been able to locate Kej Tal’s base of operations, surviving numerous engagements with numerically superior forces. The RASSILON was attached to OPERATION UPPERCUT to lead the engagement with Kej Tal’s forces. The operation was a success, but the RASSILON was destroyed. Following the completion of the operation and the subsequent inquiry into the loss of the RASSILON, Grigor applied for a transfer to Starfleet Academy as an adjust instructor. The application was accepted and he spent the next two years on Earth.
While an adequate instructor, Grigor was not particularly suited for academic life and requested a transfer to an active starship role. In 2388, he was assigned to the USS VENTURE as Chief Tactical Officer.
