Space between spaces

The " Space between Spaces" was a dimention that all the interdimentinal beings romed. All the beings came down to earth and taught the Ugha how to bulid a temple out of "solid gold". They kept their unidentified,flying,object in that temple for thousands of years. Until Indy and all of his crew retuned the skull that was lost. Then they went of in their U.F.O destroying evrything the Ugha had made. They returned back to thier land and stayed there. Nothing else is known.
