This story is a sequel to The Advent of Godzilla

Tambelon, the most majestic city aside from Canterlot and the Crystal Empire. What stood out from either of the two is the perfect quality of the tubular bells they produced. The grandest of the bells is hung high in the castle towers. Legend speaks that should the Master Bell be rung, it’s sound can bring forth great joy. The Rams and the Ponies shared the city. But one Ram didn’t want to share his city with the Ponies. Studying dark magic, the Ram was able to drive the Ponies out of Tambelon, but those that stayed and fight were placed in a gladiator arena. Princess Celestia would not tolerate his actions. A war soon broke; many of both sides did not survive. As a last measure, the Ram leader placed his life energy into the Master Bell before being banished into the Netherworld. But somehow Tambelon would return every 500 years, and the bloodshed would begin anew.

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.
