Rosetta's Cataclysm

Rosetta's Cataclysm was a series of major global climatic events took place that could easily be described as a global cataclysm with catastrophic consequences. Numerous accounts from all over the world from that period describe the start before the massive meteor storm, that the sun was getting dimmer and losing its light. Many accounts also described it as having a bluish-purplish color.
The effects were also observed with the moon – it wasn’t as bright anymore. The reduction of the light resulted in the reduction of heat on the planet, no rain, and a very long winter which resulted in crop failures and for birds and other wildlife to perish. Famine and plagues struck many areas and there were a huge number of deaths.
An Aurelian statesman described the start of the cataclysm to one of his subordinates in a letter:
* The sun's rays were weak, and it appeared a "bluish-purplish" color.
* At noon, no shadows from people were visible on the ground.
* The heat from the sun was feeble.
* The moon, even when full, was "empty of splendor"
* "A winter without storms, a spring without mildness, and a summer without heat"
* The seasons "seem to be all jumbled up together"
* The need to use stored food to last through the situation.
Further phenomena were reported by a number of independent contemporary sources:
* Low temperatures, even snow during the summer (snow reportedly fell in Utefue, which caused the harvest there to be delayed)
* Widespread crop failures
* "A dense, dry fog" in Kirbysay, Vacete and Utefue
* Drought in Hybyythia, which affected the local culture
