Week of the Midnight Sun

The Week of the Midnight Sun was a supernatural event that occurred in Egypt during the pre-Dynastic period.

Overview
It is said that an "avenger goddess" called Sakhmet struck against those who dare oppose the light and embrace the dark god Set. Those who witnessed her terrbile wrath called her "the Eye of Ra", though, in her own right she was known as "Lady of Pestilence", a terrible maiden who brought and held command over plague.

As the story goes, the sun god sent his avenging eye against the people of Khem for plotting to usurp his power over the land. In truth, the growing dominion of the Setites began to worry the celestine, and he struck out in the two ways the would hurt Set and his childer the most.

The first way was to bring the full power of the sun when the undead were strongest. The barriers between the physical realm and the Umbra were thinner back then, and so a crimson penumbral sun shined over all of Khem for almost a full week, through day and night, incinerating numerous Followers of Set as they awoke to find the light still shining in the sky.

The second method was to attack humanity itself. Sakhmet tore through Upper Egypt's villages, decimating the residents and leaving pestilence her only gift to those who survived her initial assault. What few Setites remained were unable to safely feed for some time thereafter and were reduced to feeding from carrion and other unsavory sources.

Ra eventually restored Sakhmet to a more benign aspect after her work was done.
