Biography
In 2155, Commander $𝜇$, first officer of the, sent Gardner information on an extremely advanced starship being held by the Tholians, which Archer felt would be of enormous value to Starfleet. After taking control of Enterprise from Captain Forrest in order to pursue this lead, Archer ordered Ensign $𝜇$ to transmit the relevant information, knowing that, if Forrest were able to regain command, Gardner would find the information intriguing, and issue an order for Forrest to continue the mission into Tholian space. Such a scenario did occur, and Forrest was forced to reinstate Archer as first officer upon receiving a directive from Gardner to proceed with the mission. 

Later, after Forrest had been killed and Archer had appropriated the ship, the USS Defiant (NCC-1764), Gardner responded to Archer's demand that Starfleet surrender to him by angrily stating that, if Archer were to approach Earth, he would be immediately attacked. Before the Defiant could reach Earth, however, Ensign Sato appropriated command of the ship from Archer with help from Sergeant $𝜇$. Introducing herself as "Empress Sato" upon arriving in Earth orbit, she demanded Gardner's immediate surrender.
