In 3643 BBY, the future Barsen'thor responded to a call for help from the starship Carida, which had been attacked by Sith forces. Jedi Knight Laranna Fain had defended the ship but was wounded in the process. The surviving Republic soldiers led by Lieutenant Bela Whinn then called for assistance. Sith Lord Vivicar, posing as a Jedi Master, arrived to the Carida and healed the woman but also infected her with the Dark Plague before leaving, causing her to turn on her own troops. The Jedi Consular used the shielding technique to save Fain.
