The Planaclysm (Plan-ah-clih-zim)

The planaclysm occurred beginning Lunas 22nd 1088 FA, and ending Solas 7th 5 ME.
This event heralded the end of The Age of Adventure, and began The Age of Memories, beginning when a group of the titans began a plan to expand their territory into Mytherium. The first real contact between planes was made during this age and it was shortly thereafter Dragons attempted to invade and all the shifting and holes made through the planes caused them to collapse inward and for sections of them to merge inward to Mytherium. What sections didn’t merge are believed to have been destroyed during the planaclysm and many hundreds of thousands died during the ensuing battles between mortals and titans, and in the destroyed planes.
