Dedestris was a planet located in the space of the galaxy's Delta Quadrant. The Sikarians would use their spatial trajector technology to reach this world. The Sikarians obtained a rare fabric from Dedestris, spun from the petals of a flowering plant that would only bloom in the light of Dedestris's moon.
In the year 2371, Sikaris III's Magistrate Gathorel Labin was showing Captain Kathryn Janeway the luxuries of his world, and offered her a scarf made of Dedestris fabric. (VOY episode: "Prime Factors")
