Grenyt was an individual who created a custom communications jammer. During the cyborg bounty hunter Beilert Valance's hunt for the Sith Lord Darth Vader in 1 BBY, the slicer Chio Fain noticed a device installed in the cockpit of Valance's starship, the Broken Wing, and assumed it was Grenyt's jammer. Fain believed that it had jammed the signals of the TIE fighters they encountered and destroyed on their way to the Outer Rim world of Arvina.
Grenyt was mentioned in the second issue of the 2019 comic-book miniseries Star Wars: Target Vader, written by Robbie Thompson, illustrated by Stefano Landini, and published by Marvel Comics on August 14, 2019.
