Rage of Dragons

A Rage of Dragons, or Dracorage, was a periodic Realms-wide event that occurred when many dragons went on a collective, senseless rampage, destroying everything in their path. This periodic madness seemed to be tied to the appearance of the King-Killer Star, and lasted for a tenday.

In the event of a localized Rage of Dragons, the more common label was a flight of dragons.

Frequency and cause
Rages could take place in a number of different cycles. Some took place every few decades, while others every few centuries. In Faerûn, most sages agreed that this periodic Rage was a direct result of a curse caused by the Dracorage mythal, a powerful mythal created by the elves around -25000 DR.

Extent of a rage
The exact extent of a single Rage of Dragons was theoretically tied to the exact position of the King-Killer Star when it appeared in the skies above Toril. However, in 1373 DR the lich Sammaster triggered an unanticipated Rage. The last Rage of Dragons resulted in the destruction of the Dracorage mythal, thus ending the magical curse upon dragon-kind.
