A reaction car refers to a ground-effect vehicle that the indigenous Schenor species utilized on Rhamsis Callo. While these vehicles possessed considerable speed and power, they lacked safety, agility, compactness, quietness, and efficiency. A Rebel group employed a reaction car to convey the juvenile Schenor, A'kazz, to his nest-guild, moving him from the spaceport of Chafflock in order to evade Imperial interference en route to A'kazz's nest-guildmaster, B'karitz.
