The Rupture
The Rupture marks the end of The Forgotten Age, and with it the ushering in of the Grand Age (although many consider this a misnomer).
It was at this time that a great meteor entered the Ashen lands. Crashing onto the city of Din it, wiped the grand city off the map, along with upwards of 15 million people, in one single instance. In its place lay a great cater. In its center, a boulder made of what is now called "starrite", which would be central to bringing forth the Great Age and the eventual stigmatization of magic.
14 more Starrite meteors woudl descend upon teh Ashen lands. However, of the 15 that wrought destruction, 2 remain to be unfound.
