Arzen field

Arzen fields were a type of terrain where agriculture was possible. When the weather on a Raspar system celestial body was warm, Mooxx fat could accumulate and create clouds over arzen fields, which made irrigation difficult.

Behind the scenes
Arzen fields were mentioned in a one-page weather forecast titled "Region 29: The West Fissure," written by Bob Carrau for the 1993 book Monsters and Aliens from George Lucas, a publication that collects concept designs and photographs from various George Lucas projects. Lucasfilm employee Leland Chee, who maintains the Holocron continuity database, has indicated that information contained in the book is non-canonical.
