The chaotic month of Entropy comes at the end of the year. It’s full 28 days are a mystery at times because of the complete weather changes that happen. One day it could be as hot as a desert in normal climate areas and the next, it could be as cold as the Yatil Mountain tops. Darkness might come for the whole day while another day will have the darkness and the light come at different intervals throughout the day.
No scholar has been able to predict the events of the month of Entropy and so many farmers find that to be the hardest month to take care of their crops. Many believe that this is punishment from the dieties for whatever happened before the period of Tabula Rasa. Some wizards believe it’s the very planes that interfere with the world of Erreyes during this time. One theory (created by Stondylus) is that the 13th month (another name for it as of it’s unluckiness) is a time where the arcane magic of the world rides up against the other planes causing the weather to change and natural disasters to occur more often.
In the Campaign of “The Great Theory” it was found that the dieties themselves had caused the month of Entropy due to the violent storm that rages in the northern unknown territories. Though this knowledge is only known to the Heroes of the Portal, Hulda, and Nord Cooper.
