Perched at the top of the Gregminster Palace, the Floating Garden is well known for its rare flora and fauna. Some species, such as the Black Dragon Orchid, can only be found in the imperial garden. In SY 457, the final battle of the Toran Liberation War was fought in the Floating Garden, when Emperor Barbarossa Rugner used the Sovereign Rune in order to transform himself into a three-headed Golden Hydra. Tir McDohl and the members of his entourage, however, managed to vanquish the Emperor's rune-enhanced form. After being defeated, many of his former Six Great Generals pleaded with him, trying to bring the Golden Emperor to see how his court magician, Windy, was using him.
