Tal Manan was a Starfleet officer serving in the 24th century.
At one point in his career he had served in the Starfleet Diplomatic Corps.
In 2369, while serving as first officer of the USS Endeavour he theorized that if the Borg Collective were ever faced with an overwhelming for the possibility of an alliance with the Federation could be possible. This was not a welcome view at the time. He would be vindicated later when the Borg turned to the USS Voyager for aid against Species 8472.
By 2374 he was commanding the USS Kirtland.
