Judaean Epochs

The estimated transition into the Third Epoch from the period prior, which is currently unidentified. The Third Upheaval was caused by planetwide volcanic eruptions thought to have been instigated by crossing too near to a magnetically reactive planet or planetoid, during which 99.9% of all life was wiped out.

The transitional event between the Second and Third Epochs, the Second Upheaval was caused by the slow-turned-rapid collision of multiple tectonic plates that resulted in the destruction of the smaller North Central and Northeastern Plates, and created the Great Central Range of mountains. During this upheaval, previously advanced intelligent life was rendered almost entirely extinct.

The estimated beginning of the current era on Judaea, the First Upheaval was the result of the collapse of the Great Central Range, which left the Great Central Sea in its place.
