Crystal Castle

The Crystal Castle (not to be confused with the 30th Century Crystal Palace) is the palace from which Queen Hikari and King Demande ruled over Nemesis at the start of the 21st Century. It is also the home of Princess Elyon, Princess Roxy and sometimes Sailor Pluto when she and Mamoru Endymion aren't ruling over space-time.

It's design is very similar to Crystal Palace, but has a couple of differences, including a more sloped middle spire. There is a smaller palace in the middle spire (the Dark Moon Castle) and is surrounded by lavender water and various crystal's.

 * Other working names for the castle were Diamond Palace or Quartz Castle.
