"Viola had always been warned never to open the forbidden book - the Ex Libris Noctem - but her curiosity had finally overcome her caution. As the dusty leather spine creaked under the decades of neglect, and the heavy pages began to turn, seemingly of their own desire to be read, the light of the world began to fade, and darkness spread against the sky. With a sound like the universe breathing in around her, Beasts began to stream out of the pages of the book and fly towards the city. Beasts with sharpened teeth and flapping wings.
Realising her mistake too late, Viola grabbed her broomstick with one hand and began casting a spell of banishment with the other. This was her fault, and it was up to her to fix it. If it was the last thing she did."
