The Malachor Grand Prix was a two-seater soapbox car race held on Malachor V every year to commemorate the birth of the cheating charter system. It was considered one of the most dangerous soapbox car races in the galaxy since the course, located on Mount Riggs, was bordered by rocks and trees. Each heat had 12 carts running one another, for a total of 10 heats. Brianna Reiss and the future first officer of the Enterprise (BC-348), Catalena Rinne, both entered teams using crewmembers of the Stoneship (BC-347).
