Disaster / Destruction
The last 2000 years taught the people of the world that there was no limit to the cold. On the first hour of the 5000th year a single droplet of snow is followed by a year of hallowing, deafening winds. Hundreds die.
It had first been noticed by the Elvish, which can modernly be reasoned due to their geographical location being the most southerly of the tribes. They made clothing to fight it off initially, but nothing could have prepared them for what was to come. The Dwarvish were lucky, they had their mountainous caves and chasms with which to take shelter - but it still wasn't enough to stop the cold. For one long year the winds howled and the world seemed to freeze over. If it had not been for the day of meetings, the Elvish explorers would have certainly perished. If not for the creations of all that had come before them - this year could have stood for the extinction of everything living. The mad titan had begun his sickening game of playing god.
