The structure was distinguished by a crystal throne that sat in the center of the building. All around the throne were discarded pets of the Gracca, creatures which he had either purposefully or intentionally turned into crystal statues. During the Ewoks' attempt to recover the Crystal Cloak, Gracca was in his lair, and one of his pets came to him to tell him about the Ewok intrusion. This allowed Gracca to surprise the Ewoks before they could reach his home.
