Toril
Toril is a vast and wondrous world, filled with an immense diversity of peoples and a rich, full history. For most folk of the Sword Coast, however, knowledge doesn’t extend much beyond the confines of the North, and anything “known” outside of Faerûn proper is based more in rumor than in fact.
Be sure to traverse the information by following the proper campaign you're currently in, ex. Waterdeep in one campaign might differ from another campaign.
