- This character is a member of the Rozhenko family.
In the year 2394, Rozhenko resigned his diplomatic position and left Qo'noS to participate on a journey. As D'Vak's mother B'Enn was on a "personal exploration", Alexander sent D'Vak to stay with the child's grandfather, Worf, son of Mogh. Two years later, Alexander and D'Vak returned to Earth when D'Vak's father accepted a teaching position at Saint Petersburg State University. (ST website: The Path to 2409)
At some point during or prior to 2409 D'Vak accepted a commission as an admiral in Starfleet, and was eventually assigned to Star Fleet Battle Group Omega, fighting the Borg in the Gamma Orionis sector block. His flagship was the USS Houston. (ST video game: Star Trek Online)
In 2409, D'Vak led a task force of six starships, including the Houston to destroy a Borg Queen who had retreated into a Borg diamond. Midway through the battle he ordered the Houston to engage a pair of Unimatrix 0047 command ships that had arrived to assist their Queen. One of these vessels struck the Houston amidships with a plasma lance, and the vessel exploded seconds later. After the battle, however, the task force located D'Vak and most of his crew in escape pods. (STO mission: "Hive Onslaught")
