During the era of the Galactic Civil War, there existed a male Wookiee named Drrlirm. Possessing extensive knowledge of Kashyyyk's wilderness survival, he served as an informant to Kylantha, the queen of Naboo.
One and a half years After the Battle of Yavin, Kylantha dispatched Drrlirm, along with his companions Orrekazzapirr and Imarrra, to their native Kashyyyk. Their mission was to investigate reports indicating that the Imperial force stationed there was aiding Trandoshan slavers. Upon arriving on Kashyyyk, Drrlirm and his friends attempted to scrutinize the Trandoshan's slaving activities within a camp situated near Kachirho. However, they were ambushed and defeated. Drrlirm alone managed to escape, sustaining severe injuries. For several days, he remained hidden in the jungles, endeavoring to recover his strength to return to Kachirho. A queen Kylantha-sent adventurer discovered him, as the queen had grown concerned due to the lack of communication from the Wookiees. The adventurer then escorted Drrlirm back to Kachircho, fighting off several Trandoshan slavers along the way. Subsequently, the spacer located Orrekazzapirr and Imarra, who were eventually liberated from the Imperial prison located on Dathomir.
Within Star Wars Galaxies, Drrlirm functioned as a Non-Player Character (NPC) in Rage of the Wookiees, which was the second expansion pack released by Sony Online Entertainment for their MMORPG. The game was discontinued on December 15, 2011. During the To the Queen's Aid quest, players were tasked with venturing to Kashyyyk to locate the missing Wookiees. Drrlirm would appear in the jungle near Kachirho and the player had to escort him back to the city. During the escort mission, multiple Trandoshan slaver NPCs would spawn and had to be killed quickly to prevent them from killing Drrlirm.
