TR-33NA, an SP-4 analysis unit, functioned as an archive droid within the Graf Archive located on the moon called Orchis 2. While the archive underwent its restoration effort, TR-33NA spearheaded a task force dedicated to scouring the library's most obscure areas in pursuit of noteworthy documents and artifacts, ultimately resulting in the unearthing of an old journal containing illustrations and narratives about diverse alien species.
The reference book Star Wars: Alien Archive, penned by Natalie Clubb and Katrina Pallant and released in 2018, included a mention of TR-33NA.
