Eban, a molecular botanist from a marsupial species, was present at a Vector Day celebration. The party was thrown by Mrp-Mrp Poo, a Quenk jazz musician. While there, a segment of Tireis Blackandwhite, a female of a species capable of self-division, expressed her desire to depart with the attractive Eban, leading to a dispute with her other segment. Throughout the evening, Eban sported his formal Helmet of Fourteen Confusions; journalist Dyslogia Twang noted that while it enhanced his appearance, it also triggered spontaneous orations composed in the language of the 41st eon whenever he walked past radar detectors.
Eban's name appears in Monsters and Aliens from George Lucas, a 1993 publication. Leland Chee, an employee of Lucasfilm responsible for the Holocron continuity database, has stated that the information within this book is considered non-canonical.
