Tren Renalla was a female Bajoran Starfleet officer in the early 25th century. In 2409, Captain Tren was in command of the deep space science vessel USS Gold as it surveyed the Jenolan Dyson Sphere. The Gold was stranded there when the sphere jumped into the Delta Quadrant. Captain Tren was grateful when the USS Dyson arrived through an Iconian gateway and rescued the Gold.
