Dwell in Darkness
The Spellplague was a disaster that struck Realmspace on 29th Tarsakh, the Year of Blue Fire, 1385 DR, and was caused by Mystra’s assassination at the hands of Cyric and Shar. With the goddess’s death, the Weave, the universal structure of arcane forces, convulsed. It continued for a decade, leading to the Wailing Years, during which arcane magic ceased to function and the planet of Toril was transformed.
A mystical blue fire exploded from magical items with charges. Artifacts turned into inert items. Magical items that could be activated manually were unpredictable when used. Rifts in the earth were formed from the magical waves of fire. Elminster replenished some of Mystra’s divine energy and she returned as the goddess of the Weave.
Upon her return, most magical items that were still intact returned to their normal function. Artifacts disappeared, many say because Mystra wanted them hidden from evil hands. Currently wizards and sages are reluctant to craft or repair items. Identification of items isn’t as easy as before as some items have been affected by a aura unlike anything seen before.
