When Admiral Leeta failed to score victories in the prime universe of 2410 and at the Battle of Procyon V in the 26th century, the Emperor of the Terran Empire dispatched the ISS Tempus, ISS Pastak and ISS Poh to intercept the imperial flagship, the ISS Enterprise, and relief Leeta of her command. Captain Nereda of the Pastak taunted Leeta but lost control of the situation when Leeta used a prefix code to gain remote control of Pastak's shields. The Enterprise destroyed the Pastak, and the two surviving Mobius-class swore fealty to Admiral Leeta. (STO blog: Aftershocks)
