Your Princess is in Another Castle

I don't think this really qualifies as a spoiler. I just felt I should mention that in the Rhapsody universe, Luna doesn't live at Canterlot castle. There are two reasons for this.

1)

If she is resting/living in Canterlot, why would she need to fly in from outside of the bubble?

2) Luna seems to care a lot about the past, and likes darker things in general. I like to imagine she lives in the castle of the royal pony sisters, which is now surrounded by the Everfree. This is why she rushes to Celestia with news from the Everfree in the prologue chapter of my story.
