Toril, occasionally known in the past as Abeir-Toril is the name of the planet on which the Forgotten Realms is primarily set and of which Faerûn is a continent.
The name is archaic, meaning either “cradle” or “life” in an extinct and forgotten language. It consists of various continents and islands, including Faerûn, Kara-Tur and Zakhara in the central supercontinent and, throughout most of its history, Anchorome, Maztica and Katashaka in the western supercontinent. Following the Spellplague, however, at least Maztica (and likely Anchorome as well) was replaced by the continent of Returned Abeir. There is also one large and very mysterious continent east of Kara-Tur called Osse whose nature and inhabitants are all but unknown.
