Meditation spheres were spherical attack craft ten meters in diameter. They resembled giant, floating eyeballs with batlike wings. At the heart of the meditation sphere used by Naga Sadow was the Sith Lord's meditation chamber. The chamber had jagged walls that sloped inwards and at the center the Sith Lord would crouch and focus his dark side powers that allowed him to amplify his intentions and send them out over great distances to control his armies and ensure victory for his forces. Thanks to the Sphere, the Dark Lord could create Illusions and make them real enough to cause damage, giving him an edge in battle.
