The Sundering refers to two events that occurred in the fictional timeline of the Forgotten Realms campaign setting of the Dungeons & Dragons role-playing game. It is also the title of both a series of novels published by Wizards of the Coast and a multimedia project Wizards of the Coast used to transition Dungeons & Dragons from 4th Edition to 5th Edition. This project explored the Second Sundering story and included the aforementioned book series, the free-to-play mobile game Arena of War developed by DeNA and an adventure series for the 4th Edition D&D Encounters program.
