Dracorage mythal

Created during the Time of Dragons by High mages of the Fair Folk, this High Magic effect tied a Faerun-wide Mythal to the King-Killer Star.

The Dracorage mythal encompases roughly a 250,000 square mile area where the King-Killer Star is visible over Faerun and causes all Dragon and Dragon-blooded creatures to slowly become more agitated and reckless, eventually becoming little more than raging beasts.

Reversal/Healing
There are few means to stop the effects of the Dracorage mythal completely by natural or magical methods. Most spells are ineffective and even Wish or Miracle spells only mitigate the effect if cast daily. The extremely rare spell abate Dracorage is perhaps the most effective spell in calming the effect of the Dracorage.

Beyond these limited magical means the only other reprieve is leaving the area of the Dracorage mythal completely.
