"For an illuminating example of pan-species cooperation, don't miss the moon of Alchenaut, where palm-sized furballs that I named o'cerrys act as a predator warning system for thousands of other herbivores."
―An excerpt from The Jedi Path: A Manual for Students of the Force, by Jedi biologist Bowspritz[src]
The o'cerry, one of the herbivore species native to Alchenaut
Alchenaut was first mentioned in the 2010 reference book The Jedi Path: A Manual for Students of the Force by Daniel Wallace.[2] In September 2012, Alchenaut system was added in the Online Appendix of The Essential Atlas at StarWars.com.[1] Co-authored by Wallace and Jason Fry, The Essential Atlas is a third-generation Essential Guide focusing on the astrography of the Star Wars universe.[4] The appendix placed the Alchenaut system in the Alchenaut sector of the Expansion Region, at the grid coordinates L-16.[1] Though the moon of Alchenaut is not said to be within the eponymous system in The Jedi Path,[2] Fry has stated that "planets not assigned a system in [a] published source can be assumed to reside in [the] system of [the] same name."[5]
↑According to The Jedi Path, the book was first published "a decade or more after the end of the New Sith Wars in 1000 BBY." This is taken here to mean the year 990 BBY.
