Long ago, after the sealing of Discord and Sombra, after the founding of Equestria, there was great peace. That is until a great crimson beast arrived and consumed houses, crops and livestock. The Princesses of the Sun and the Moon fought against the beast, but though their efforts were rather fruitless, they were able to drive the beast to the badlands. The Princess of the Moon thought this wasn’t enough and so painstakingly convinced Ursa Major to vanquish the beast. Since then, no one has heard of the beast, and knowledge of the experience was gradually reduced to legend. Equestria was safe again.

Until now.

When Princess Luna finds out that the beast still exists, she does everything in her power to rid the potential threat. Cosgrove must prove Schnookum's innocence.

First chapter in the Old Timeline, taking place in the middle of Season 4.
