Yareth was a Rakhari girl sentenced to death for the crimes of her father, Croden. Yareth escaped execution by hiding in a stasis pod on an asteroid in the Chamra Vortex.

In 2369, Croden tricked Odo into helping him free his daughter by persuading the Changeling that there were others of his kind on the asteroid. With Odo's help, Croden revived Yareth. Rather than turning them in, Odo transferred Yareth and her father to a Vulcan ship. (DS9: "Vortex")
