The individual was the friend of Amilyn Holdo (pictured).
A Spira planet resident, located in the Core Worlds, owned a mansion and was a friend to the rebel captain Amilyn Holdo. Sometime between the years of 3 ABY and 4 ABY, Holdo requested to borrow the mansion for a few days from her friend. She intended to attend an auction in order to obtain a strikeship that once was the property of the Nihil marauder group. This was part of her scheme to assist the Rebel Alliance with their fuel shortage. Holdo was accompanied by fellow rebels Leia Organa, Luke Skywalker, Lando Calrissian, Lobot, and Chewbacca, as she felt they were due for a respite from the ongoing Galactic Civil War against the Galactic Empire.
Following the rebels' failure to win the auction, they stole the ship's Path engine component and made their way back to the mansion. However, they were pursued by a squadron of TIE fighters. As the rebels escaped, the TIEs obliterated the mansion. This caused Holdo to lament that her friend would "kill her" due to the mansion's complete destruction.
The identity of Amilyn Holdo's friend was revealed in the twenty-ninth issue of the Star Wars comic series of 2020. Charles Soule wrote the issue, and Marvel Comics published it on November 2, 2022. Before the comic's release, a preview article concerning the issue was released on StarWars.com on October 27 of that same year.
