At the end of the Clone Wars, Darys managed to escape Order 66, the Contingency Order used to wipe out the Jedi Order by Dark Lord of the SithDarth Sidious. Instead of fleeing from the newly formed and Sith controlled Galactic Empire, Darys followed in her former master's footsteps and joined the Empire, disavowing her Jedi heritage and falling to the dark side of the Force. Becoming a member of the Imperial Inquisitorius, Inquisitor Darys hunted down her brother and sister Jedi per the Emperor's orders. While making a sweep over Belsavis during the hunt for Jedi Master Plett, Darys' agents captured the young Lagan and Roganda Ismaren after the siblings had evacuated the planet with the so-called Children of the Jedi. When they were brought before Darys, the ruthless Inquisitor ignited her lightsaber in Lagan's heart and let him die before his sister's eyes. Playing on this, Darys was able to turn the horrified Roganda Ismaren to the dark side.[1]
Later, Inquisitor Darys joined Grand InquisitorTorbin and Inquisitor Antinnis Tremayne in the hunt for the recently discovered Arden Lyn, an ancient threat reawakened from a millennia long slumber. When the team tracked Lyn down, the powerful Force-wielder seriously injured Tremayne and killed Darys before Torbin was able to remove Lyn's right arm with his lightsaber and disarm her.[1]
