I know this likely accounts to nothing, but I noticed that in the Half Pint, Moonlight Suite in Crossing, there is a painting that says that the eleven planets are depicted. I found this odd as there should be 12 planets. Was just curious if there was ever a time in Elanthia history where it was thought that there were only 12 planets.

Half Pint, Moonlight Suite
A crescent-shaped, billowing bed dominates the center of this room. The ceiling is painted midnight blue, with glowing gems twinkling in rhythmic sequence like some perfect night sky. On the deep blue walls are depictions of the eleven planets and scenes of the Immortals who govern them engaged in feasting and merriment.
