Time of Troubles

Also known as the Arrival, the Avatar Crisis, and the Godswar, The Time of Troubles lasted from 15 Kythorn to 15 Marpenoth in the Year of Shadows, 1358 DR. During the Time of Troubles, the gods were thrown from their homes in the Upper planes to walk Toril in the mortal Avatar forms. Each of the Avatars of the Gods spent the Time of Troubles in their own way. Some sought refuge away from all mortals, while others recruited armies to do their bidding. Several Gods fought in open battle with one another, causing the deaths of many deities. With the gods cast out of the Upper planes, divine magic ceased working at all, unless the divine spellcaster was within one mile of their deity's avatar. Mystra, the goddess of magic who tended the magical Weave was destroyed. With her loss, Arcane magic became wild and dangerously unpredictable. Spellcasting had chaotic results. Sometimes spells had the normal, desired effect. Other times, spells would result in no effect at all. Some spells could have random Wild Magic effects with the resulting spell becoming devastatingly powerful.
