Spaarti Cylinders
originally designed early in the Clone Wars by Spaarti Creations on the planet Cartao, these specially-designed canisters provided a more modern method for the Old Republic to generate clone troopers for the Army of the Republic. During the battle for control of the planet Cartao, most of these cylinders were destroyed. Then Chancellor Palpatine, however, saved a number of them in his warehouse hidden within Mount Tantiss, on the planet Wayland. These cylinders were lost for decades until Grand Admiral Thrawn rediscovered them. He used them to clone troopers to augment his own forces, including the captured Dreadnaughts of the Katana Fleet, during the early years of the New Republic. The only known drawback to the use of Spaarti Cylinders was that they tended to create clones that went insane farily rapidly, as a result of their accelerated growth cycle.
