Long after the events of Boast Busters, and after getting kicked out of Ponyville more times than the number of stars on her hat, a rage-filled Trixie swears to learn about this ‘magical friendship’ nonsense once and for all, so that she’d finally have some real magic to show off. She starts off by painting herself lavender, and enlisting the help of a particular pink pony.

I came from a shimmering pool of crystal clear water. I moved from the dark forest to the cheery village that was built nearby. I was once a happy pink pony, but then things took a turn for the worst.

Little is known about the creature cast in stone. On the night of an eclipse, an unknown horror is released into the Everfree forest, seeking out the blood of a particular purple pony.

Armed with a mysterious black book and with the help of her friends, Twilight is forced into a terrifying adventure of uncovering secrets and finding a way out of her nightmare. But the problem is that nopony knows what a Draconequus really is.
