According to Earth intelligence Kiva was the daughter of a Lucian Alliance warlord named Masson, one of the higher-ups in the organization who is known to be powerful and brutal. Kiva herself has a cold, no-nonsense demeanor, and seems willing to do whatever is necessary to achieve her goals -- including torture, and even executing her own people.
Kiva was likely the Alliance contact for David Telford, a Colonel in the U.S. Air Force who infiltrated the Alliance only to be caught out and brainwashed to become a spy for the enemy. During the incursion of Destiny Telford's brainwashing was broken. When Kiva discovered that he was transferring computer controls back to the crew from Earth, she and Telford shot each other.
Colonel Telford survived his injuries, but Kiva died on the operating table.
