Princess Celestia is due to arrive in Ponyville in a few hours. Nothing is ready. The town is being invaded by a swarm of parasprites. Pinkie Pie has gone completely loco-in-the-coco and is rushing around Ponyville collecting random musical instruments.

Can you engineer an eclipse to order? You can if you know the right princess and ask nicely.

In a world where the movement of the sun and moon is down to the whims of alicorn princesses, other ways must be used to keep track of time. High up in the mountain above Canterlot, there lies an old abbey, home to the Order of the Time Turners, a monastic community of ponies founded by Starswirl the Bearded, who follow a strict timetable of daily duties to regulate the length of day and night. After following the same routine for over seven hundred years, things are about to change.

Princess Celestia’s School for Gifted Unicorns is famous across Equestria as a center of academic excellence. Only the best and brightest unicorns are offered places, selected by their academic merit, magical ability and passion for study.

Maud and Pinkie Pie explain all about the rock cycle. With chocolate.

Twilight Sparkle is aware that the manipulation of matter at the sub-atomic level is a potential source of enormous amounts of free energy. She also knows that this is extremely dangerous, and that these spells are only for the highest level unicorns. She is therefore somewhat concerned to discover that Pinkie Pie has found another way to do this, with a curious contraption in the basement of Sugarcube Corner.
