USS Berlin
From Star Trek: Theurgy Wiki
The USS Berlin was an Excelsior class Federation starship operated by Starfleet in the late 24th century. (Source: Memory Alpha)
In 2376, Diadeniera Drovo graduated from Starfleet Academy and was assigned to the USS Berlin set to patrol the Romulan Neutral Zone.
In 2378 (Stardate 55031.5) the Berlin’s Deputy Chief of Security died and Drovo was promoted to the position Later that year the Berlin’s Chief of Security was discovered to be a saboteur and a spy leaking pertinent information to unauthorized parties. In spite of the overwhelming case against her superior that she brought to the captain of the Berlin she was instructed to keep quiet and be thankful for all the career opportunities she was given. While no one came right out and threatened her future in Starfleet the writing was on the walls so when the USS Berlin returned to Earth Lieutenant Drovo transferred off the Berlin to the USS Harbinger.
(While not explicitly stated it is possible the Berlin officers were compromised by the sentient parasites that have taken over Starfleet Command. It is likely that the Berlin is currently part of Task Force Archeron).
