The Centra built mobile shelters the size of small cities, able to hover and cross gentle terrain, and which are also capable of planting themselves in the ground. Only three are known to have survived until the present day, in the form of Balamb Garden, Galbadia Garden, and Trabia Garden. According to the Final Fantasy VIII Ultimania, the Lunar Cry that destroyed Centra brought the Crystal Pillar from the moon and buried it under the Centraian soil, to be dug up later by Esthar.
