In 1001, 57 dragons broke into the world. Because few of them were discovered until 1002, scholars believe the dragons must have taken several months to grow.
The dragons commanded elemental powers that threatened to destroy the balance of nature. To prevent the world from unraveling, most dragons had to be slain. Some were killed by nature spirits, but most were killed by the people the deities had created to protect the world. This was their first test.
Some dragons integrated with the laws of nature and were allowed to survive. Nearly every culture on Edgewhen was impacted by the Time of Dragons.
