Devon Riyannis

Devon Riyannis, née Yarvo, was a male Trill active as a non-commissioned officer in the Federation Starfleet in the mid-24th century.

Devon spent thirty years in Starfleet with a transporter officer rating, reaching the grade of master chief petty officer before hitting mandatory retirement. During part of his career he served with then-Ensign Jadzia Dax, and remarked that she was smart to pay attention to her noncoms.

He was married and divorced twice and did not have custody of his children.

Devon died of a stroke two years after retirement.

In 2410 his identity was placed in Kanril Eleya during Birail Riyannis' zhian'tara ceremony. Birail informed him of Jadzia Dax's death in 2374, and that his grandson had become first officer of the USS Wolf 359 and would be in the Delta Quadrant with the joint Federation-Klingon-Romulan fleet that included the USS Bajor.
