In the aftermath of 'All Bottled Up', Starlight and Trixie think they've got off scot-free. Aha, but they reckoned without the keen observational skills of one Twilight Sparkle, and what followed is now documented here for posterity.
Princess Celestia was quite clearly overworked lately. Twilight just had to find a way to help. Unfortunately, the only answer she found was a bit odd.
After the events of 'Student Counsel', Sunburst discovers that Starlight's bracelet isn't just any old piece of temporarily enchanted jewellery. In fact, it's about to lead to a whole world of trouble..
After accidentally learning that each Princess has their very own secret rooms to retreat inside whenever they wish, Twilight Sparkle makes it her mission to uncover just what could be inside Princess Celestia's.
Discord knew this was coming. He knew. So did Princess Twilight. They knew. They saw it coming a mile away. Yet they let this happen anyway. Why couldn't they just let things stay the same? Who's the bigger fool?
Trixie's line of work is dangerous. But she's a careful showpony, and that's why she's only died a few dozen times in her career. She thinks this is normal.
The book was Twilight Sparkle's greatest creation – ask it any question about how your life might have been and see the answer. It is a work of genius. It is a tempting, insightful, wonderful marvel of magic. It is a terrible mistake.
