A piece of mobile technology, referred to as a disease chamber, is known to have been in the possession of the criminal known as the "Marauder of Endor."
The existence of this disease chamber was noted on a single-page wanted poster. This poster was authored by Bob Carrau for the 1993 publication Monsters and Aliens from George Lucas. This book is a collection of concept designs and photographs originating from various projects by George Lucas. Leland Chee, an employee of Lucasfilm responsible for maintaining the Holocron continuity database, has stated that the information found in the book is considered non-canonical.
