Great Collision

The Great Collision, occuring in 0, was when the Realms collidied, fractruing many realms, mixing others, and leaving the Realms as a whole incapacitated to defend itself. It was the start of the Colliderent Era. Some think it was caused by a vast wave in the Cosmic Field that was caused by the destruction of the Cursed Realm in -5 and the resulting events in the Ninjago realm. Others say it was manufactured by Carnation to provide him with a way to unravel the Realms.

It was undone by the Reorderment in 253, causing the end of the Colliderent Era and the beginning of the Field Rule Era in the Realms.
