In the episode “It Could’ve Been Great,” Peridot explains that there were supposed to be numerous Kindergartens and Spires. This would further explain my theory of Lapis’ past. Lapis wasn’t part of Blue Diamond, but she was important to Blue Diamond.

First of all, the statue of the Lunar Goddess is actually Blue Diamond.

It appears she is holding one of the spheres that was seen in a room with water on the moon base.

So in the episode “Message Received,” we see Yellow for the first time (yay!) and are also able to see her base, which looks a great deal like the moon base. Since there are murals, like the ones in Serious Steven, which just further proves that that pyramid was White/Pink Diamond’s hideout, it is safe to say that the moon base is Blue Diamond’s old base.

Now the Spire’s get their names for each ambassador that stays there. For instance, Lapis lived at the Lunar Sea Spire.

Lunar = Relating to the Moon Goddess, Blue Diamond.

Sea = Water ambassador, Lapis Lazuli.

Now if Sapphire had a spire, it may be called the Lunar Polar Spire, since she controls ice.
