Great Tearing

The Great Tearing was a cataclysmic event that changed the nature of the Universe. It marked the end of Aberrant rule on Mervona and saw the beginning of the Ancient Era.

23,000 Years before the Great Tearing, a group of Aberrants migrated from their home plane, the Aberrant Plane, to the Universe, specifically the planet Mervona, in an event known as the Aberrant Migration. They brought with them some of their gods, known as the Elder Gods. After establishing an empire across much of Mervona, they began altering the nature of the plane, to some unknown purpose. After many thousands of years, the strain on the fabric of reality was too much and the Great Tearing occurred.

The Universe's connection to the Aberrant Plane was severed, killing the Elder Gods and greatly reducing the powers of the Aberrants. The boundary between the Universe and the Otherworld was torn and some merging between the two planes took place. Additionally, the Universe's connections to the Outer Planes greatly increased.

In the aftermath, the slave races on Mervona revolted and succesfully killed most of the Aberrants, driving the remaining ones deep underground. This marked the beginning of a period known as the Ancient Collapse.
