Abeir-Toril
Abeir-Toril (or commonly referred to as Toril) is the name of the fictional planet that makes up the Forgotten Realms Dungeons & Dragons campaign setting, as well as the Al-Qadim and Maztica campaign settings and the 1st edition version of the Oriental Adventures campaign setting.
The name is archaic, meaning "cradle of life." It consists of various continents and islands, including Faerûn, Kara-Tur, Zakhara, Maztica, Osse, Anchorome and Katashaka, a sub-Saharan-like continent south of Maztica, where humanity appeared. Toril was originally the name of Jeff Grubb's personal campaign world before it was merged with Ed Greenwood's Forgotten Realms setting.
