In this world, Luna is apparently a Princess. As seen in a flashback, it is home to a huge city and castle. Not much is known about the culture of this world; only that it has a Royal Family (of which Luna is a member of).
Implifications of ExistenceEdit
-in Chapter I, after being rescued, Luna offers to take Smoosh to her homeworld and "make them Queens."
-In Chapter V, Luna has a flashback in a nightmare depicting this world while it is under attack.
