A Sea of Troubles
The Spellplague was a disaster that struck Toril two centuries ago. It was caused by the assassination of Mystra by her enemies Cyric and Shar. All arcane magic ceased to function for more than a decade, and blue fire swept across the land destroying almost everything it touched. Gnomes, however, commune with a magic not a part of Mystra’s weave, but a part of the multiverse itself, and came out from their normally quiet lives to protect largely human, elven and dwarven settlements.
