Abeir-Toril (Ai-BEER-toh-RILL) was the name of a prehistoric planet that existed before -31000 DR when Ao sundered the world into two worlds: Abeir and Toril. The name was archaic, meaning "cradle of life".
The shape of the planet was very different from either modern Abeir or modern Toril, consisting of one massive supercontinent known as Merrouroboros, which was dominated by the giantkin and the mysterious Creator races.
Abeir-Toril was one of many worlds that appeared after Ao crafted Realmspace out of the Phlogiston. Though barren and devoid of life, creatures of manifest entropy and elemental nature known as the primordials began to appear in Realmspace, coveting those worlds. Unknown to the primordials, the first gods also began to appear in Realmspace. Selûne and Shar were the first ones, and they began to create life on the world of Abeir-Toril, creating the goddess Chauntea and the sun to sustain that life.
When the twin goddesses became aware of the threat of the primordials, they rallied all the gods to defend the virgin worlds, even summoning gods from other dimensions to aid the native gods in the war. This conflict was later known as the Dawn War. While the gods and primordials battled for ages, life flourished on Abeir-Toril.
It was the end of the Shadow Epoch, during the last period of the Days of Thunder, that a conflict between the titans and the batrachi sparked. To defeat their enemies, the batrachi summoned many primordials from their imprisonment. The gods quickly moved to battle their ancient foes, and a primordial called "Asgoroth the World Shaper" hurled an ice moon down to the surface of Merrouroboros in an event known as the Tearfall, intending to destroy the world she could not claim as their own.
It was this action that finally spurred Ao to action, leading to the "changing of stars", in which the world was separated into two twin planets, Abeir and Toril. Ao gave the primordials control over Abeir, while retaining sovereignty over Toril for the gods.
