The Enigma Box

This magical artifact was crafted by Eras Abimeur, the powerful sorcerer and Warden of Iraelon. Used as an ultimate deterrent to the catastrophic destruction of war that threatened Iraelon, the planes and all reality during the Great War, the Enigma Box now has been lost to time. Some say that Eras destroyed the box and himself when he used it against the warring armies and forced the armistice. Others however say the box was hidden away to be guarded by the next Warden, in case a time would come that such a powerful item is needed again. Ultimately though it is known for its power. Blessed by Mystra herself this item's immense power caused the Sundering of the continent, turning the world of Iraelon into what it is known today. The Shattered Isle that was left behind it's destruction still to this day feels the effects of wild arcane forces, creating a devastatingly dangerous place to venture into.
