Abeir

Abeir was one part of the prehistoric planet called Abeir-Toril.

History
After the Primordials created this world, the gods interfered by wanting to create living beings to live on Abeir-Toril. This sparked a war of unbelievable destruction which ended when Ao separated the world into Abeir and Toril, each located in their own material plane. The gods ruled Toril, the primordials Abeir.

Abeir was similar to Toril in many ways, though obviously changed due to its different history. However, like Toril it contained an Underdark inhabited by drow, and it was home to most of the races that inhabited Toril.

During the event called the Spellplague both worlds merged for a certain time.

The largest part of Abeir on Toril lay off the Sword Coast, in the Trackless Sea and was ruled by dragons, though their slaves included humans, dwarves, dragonborn, and, more rarely Tel'Quessir. The slave races were very rarely given to rebellion.
