Davidia was a presidential retreat planet leased to various planetary leaders for summits, conferences, or vacations. The staff at Davidia transported huge sections of the biospheres of their client's planets in order to make them feel more at ease. Romana II and Leela visited Davidia after Romana decided to take a leave of absence due to Pandora's influence over the Matrix. Davidia had six moons. Two of these moons orbited in a retrograde motion, meaning they moved in an opposite direction to the other four. (AUDIO: Spirit)
