Tiffany Karen Amber Phoenix was born in the Phoenix Memorial Hospital in Phoenix, Arizona on November 1, 2014, at 6:30 A.M. to her mother Jennifer Mabey and her father Firenaut. Tiffany was later separated from her family when the escape pod that she was strapped into passed through a chronotransdimensional wormhole created by the implosion of Bernard's Star The phenomenon sent her to the 25th century while at the same time stranding her twin sister in the 24th century.
Young Tiffany did well to take care of herself, as she was adopted by foster parents and entered Starfleet Academy on August 21, 2464, and graduated in 2468 with honors as the youngest person to ever graduate from the Academy.
Although Ensign Tiffany's first assignment was recorded as onboard the U.S.S. Kittihawk NCC-3459 as a medical technician, her actual first assignment was onboard the U.S.S. Enterprise NCC-1701-D. She had to re-enter Starfleet Academy in the 24th century. Shortly after her mission, she was lost in a temporal rift, that sent her back to the Kittihawk. While on the Kitthawk she was promoted to the rank of Lieutenant.
When Lieutenant Tiffany was transferred to the U.S.S. Ranger NCC-6100, she also accepted a promotion to Lieutenant Commander. She served aboard the Ranger at the helm and as the Captain's advisor. She remained aboard the Ranger and became the second in command and earned the rank of Commander when the First Officer was killed on an away mission.
Commander Tiffany was promoted to Captain and was given her first command with the U.S.S. Flagstaff NCC-85230-A. She was later promoted to Admiral for her brave efforts in defeating the Borg in the Beta Quadrant.
In 2474, Admiral Tiffany's ship was equipped with temporal coils, thus allowing time travel. In her first temporal mission, she crossed paths with a man named Firenaut, Captain of the U.S.S. Phoenix NX-4096. Having spent the greater part of her life by herself, or with foster parents (the Macintoshes--where she got the Macintosh surname--the same family, one generation after Priscilla), Tiffany did not remember her real parents. It was not until later temporal missions that Tiffany found out that this man was her father and that the woman she had long believed to be her great aunt, Priscilla, was actually her twin sister.
Admiral Tiffany is now together with her father, Firenaut, and her sister, Priscilla Monique. Tiffany has two children. The older child, Jason is presently a Lieutenant Commander aboard the U.S.S. Hood. The younger child, Aurora is 18 years old and in hiding from those who would use her immense control of time as a weapon to either have total control for themselves or cause mass destruction. Aurora--along with Tiff--is the key to the Future. The two must never be separated in time or the timeline will collapse. Tiffany's father, Firenaut, is the key to the entire family. Without him, the entre family would not exist.

Tiffany's Bio

Addendum from The Federation Bureau Of Temporal Investigation

Although Admiral Tiffany is a highly decorated and respected admiral in Starfleet, she is still a wanted felon for the repeated violations of all 47 Temporal Directives including the Temporal Prime Directive on all accounts. She may be highly revered in Starfleet, but she is considered "reckless and uncaring" of the preservation of the timeline. We feel that extreme caution should be warranted when in the prescence of this admiral, even though Starfleet Command denies any reason for caution. There is concern that this admiral may never be "set straight" because her father is a Temporal Agent, but we feel otherwise.
