These are, as stated by the name, the series upon series of caverns behind the falls. The first is the main hall, well lit by some magic unguessed by any that didn't live here and have the full blood of the Sapphires. Past this, you would find three sets of stairs, beautifully wrought into solid stone of grey, winding down to three different areas. The center leads to the dining hall and ballroom of Anoria, as well as the 'suites' of the original 7 Sapphires and the Lords and Ladys that live today; the left-most to the servant's quarters and all their work places; the right to the quarters of the residents of Anoria.
