Rage of Dragons

A Rage of Dragons, or Dracorage, is a Realms-wide event that occurs when many dragons go on a collective, senseless rampage, destroying everything in their path. This periodic madness seems to be tied to the appearance of the King-Killer Star, and lasts for tendays. In the event of a localized Rage of Dragons, the more common label is a "Flight of Dragons."

Frequency and Cause
Rages can take place in a number of different cycles. Some take place every few decades, while others every few centuries. In Faerûn, most sages agree that this periodic Rage is a direct result of a curs 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 is theoretically tied to the exact position of the King-Killer Star when it appears in the skies above Faerûn. However, in 1373 DR the lich Sammaster triggered a unanticipated Rage, detailed in The Year of Rogue Dragons trilogy.

This most recent Rage of Dragons resulted in the destruction of the Dracorage mythal, thus ending the magical curse upon dragon-kind.
