Imperial, a fathier of the female variety, reproduced with Virtuous Velocity, ultimately resulting in the birth of Shifting Sands in the year 29 ABY.
Around the time of 34 ABY, Shifting Sands had risen to the status of a racing fathier located on the planet of Cantonica. Race programs identified Imperial as the fathier's dam, and one such program was collected by Resistance mechanic Rose Tico, who then included it in her personal diary.
