A rubber-root can be classified as a specific kind of root. The detective named Erno started to chew on this item not long before the events of the Coronet City revolution on the planet Corellia, following his apprehension of Oblivion, a member of the Acolyte of the Beyond, for the act of defacing a wall located in Coronet City with graffiti depicting the mask of the Sith Lord known as Darth Vader. Erno's assessment of the rubber-root's flavor was that it resembled the bottom of a boot, but it served the purpose of occupying his mouth in place of using stimsticks.
