Melwendian

The Melwendian period is the middle period of the Epilithic era, lasting from 40 to 3.5 million years ago. It is named after the Kingdom of Melwende, one of the warlord states that seceded from the Kingdom of Almador.

During the course of the Melwendian period, the climate began to shift in distribution during a period known as the Great Climate De-Lateralization. In the Cuiciloan period and before, climate was associated mostly along the lines of latitude and with rainfall patterns. However, shifts in the world's magisphere caused by an unknown force gradually "spaghettified" air and sea currents, randomizing where cold and warm biomes were located on the surface. This caused a series of moderate extinction events throughout the Melwendian.
