Twilight Sparkle has found herself feeling a bit lonely in Canterlot, even with Spike for company. And her first friendship council isn't scheduled to meet for at least another week. What's a princess to do?

Why, invite some of her other friends over for a sleepover at the castle of course. Twilight reaches out to her old Canterlot friends, offering them an opportunity to spend the night in the royal palace with her. They all accept.

Even though Twilight is the supreme ruler now, she still wants to make time for her friends and catch up. The rest of the group, meanwhile, are curious to know just what it's like to have an entire castle and its staff under your command.
