Ivies held the rank of captain within the Galactic Empire during the Imperial Era. During 3 ABY, this officer commanded a contingent of snowtroopers tasked with uncovering evidence of the Rebel Alliance at Echo Base located on Hoth, a planet situated in the Outer Rim. After several weeks of searching, one snowtrooper observed the arrival of a transport intended for the rebel contraband that the troopers had collected, commenting that it was time for their departure. Another snowtrooper responded by stating that Captain Ivies had instructed them to continue their search for rebel signs. The first trooper then retorted that they had been stationed at the base for weeks, finding nothing but snow, and concluded that the rebels had likely already left.
Ivies received a mention in the first issue of the Star Wars: Doctor Aphra comic series of 2020. Alyssa Wong penned the issue, which Marvel Comics released digitally on May 4, 2020. Before the comic's official release, Ivies was mentioned in a preview article featured on StarWars.com on March 25 of that same year.
