Set was originally created during the What's The Story? campaign on StarWars.com, in which Hyperspace members were allowed to author backstories for various background characters from the Star Wars films for inclusion in the StarWars.com Databank and canon. The particular "Maxiron Agolerga" entry, written by Tim Veekhoven under the handle "Sompeetalay," covered Agolerga around the time he was solicited to oversee the Skywalker–Amidala unity, as seen in Star Wars Episode II: Attack of the Clones, establishing Set and Veré as legendary characters in its text.[1] He was later mentioned in Veré's entry in The Complete Star Wars Encyclopedia, which was released in 2008.[3]
The eternal lovers' motif was borrowed from a famous work of J. R. R. Tolkien related to his The Lord of the Rings series, a distant prequel entitled The Tale of Beren and Lúthien, which described a mortal man named Beren's romance with an Elf-maiden, Lúthien. Veekhoven named Set after the EgyptianSet, god of the desert, storms, darkness, and chaos.[4]
