Chaleydonia, which is also referred to as the Crystal City, functioned as the capital city for the planet of Christophsis. This modern city was constructed using building materials composed of organic crystal. Within the city, at a tower, Count Dooku and Asajj Ventress engaged in their final confrontation. During the pacification of Christophsis event in 3 BBY, three Imperial Star Destroyers executed an orbital bombardment upon the city from orbit.
