Gracca's abode served as the dwelling for the being Gracca. It was situated at the summit of the Floating Mountain found on the Forest Moon of Endor. This edifice was constructed from crystals conjured through the might of the Crystal Cloak. Gracca, having pilfered the Crystal Cloak from the Ewoks residing in Bright Tree Village, fashioned this structure, placing it at the mountain's apex. The construction featured only diminutive apertures, facilitating entry for Gracca's minions, like the flying flowers, into his sanctuary. Conversely, the building's apex remained exposed to the heavens, enabling Gracca to depart his lair via flight whenever he wished.
The distinguishing feature of the structure was a crystalline throne positioned centrally within. Surrounding this throne were the abandoned companions of Gracca, beings transformed into crystal effigies, either deliberately or inadvertently. During the Ewoks' attempt to reclaim the Crystal Cloak, Gracca occupied his lair, and one of his animal companions approached him to inform him of the Ewoks' incursion. This intel enabled Gracca to ambush the Ewoks before they could arrive at his abode.
