Abeir-Toril
Twin spheres of magic and myth defining the Forgotten Realms Material Plane.
Abeir-Toril represents the twin-world system central to the Forgotten Realms setting within the Dungeons and Dragons multiverse. While Toril is the primary planet where most adventurers explore, home to continents like Faerûn and Kara-Tur, Abeir serves as its mysterious sibling world, originally part of the same planet before the Tearfall (or Sundering of the World) separated them, an event that predates the Dawn War. These spheres share a deep magical history, often described in lore as once being a single world before a cataclysmic event split them apart. Their relationship defines much of the cosmological structure for campaigns set in this region, influencing magic, travel, and the flow of divine power across the realms.

Background
Historically, the worlds were joined as a single planet before the Tearfall (or Sundering of the World) separated them, an event that predates the Dawn War. This ancient separation is distinct from later events; however, the chaotic energies released during the Spellplague caused Laerakond to merge into Toril's Trackless Sea, displacing islands and replacing the location formerly occupied by Unther/Tymanther, rather than physically swapping places with entire Torilian landmasses.
Toril remains the stable heart of the setting, populated by diverse races and nations that rise and fall over millennia. Abeir, conversely, is frequently depicted as a harsher environment, often associated with dragons and ancient powers, but it is a godless world where inhabitants simply lacked divine presence, not necessarily opposing Toril's deities. Travel between them is perilous, usually requiring specific portals or high-level magical rituals.
The connection between these spheres influences how magic functions in the setting. Certain spells may behave differently when cast near the boundaries of their influence. This duality provides a rich backdrop for stories involving cosmic conflict, where the balance between order and chaos is maintained by the separation of these two great worlds.
