The Spellplague

Plague / Epidemic

The Spellplague, called the Blue Breath of Change by the inhabitants of Toril was a disaster that struck Realmspace and even the planes themselves on the date of Tarsakh 29 in the Year of Blue Fire, 1385 DR, and was caused by Mystra's assassination at the hands of Cyric and Shar.It continued for a decade, leading to the Wailing Years, during which arcane magic ceased to function and the planet of Toril was transformed.   By 1395 DR, the majority of the effects of the Spellplague had come to an end and most arcane magic had returned to a semblance of normality, with a handful of major changes to the way spells are cast. The Empire of Netheril came across the Lost Vale and displaced the saurials there into the Underdark.
