Dryditch Fever

Dryditch Fever was a deadly illness that would make one weak and confined to bed. The cure is the Flowers of Icetor.

When this disease came around during the time of Abbess Vale, the first known creature afflicted with it was Thura, one of the stoats who stole the sword of Martin the Warrior. He died shortly afterward. Then many of the Abbey members began to come down with it, and a few unfortunately died before the cure was brought back from the Northlands.
