Abeir is a fictional world in the Dungeons & Dragons universe, primarily associated with the Forgotten Realms campaign setting. It is often described as a parallel dimension to Toril, the main world of the Forgotten Realms. Abeir features unique landscapes, cultures, and creatures, distinct from those found in Toril. The world of Abeir was originally created as a result of the separation of the two realms during the events of the Spellplague. This event altered the fabric of magic and reality, leading to the emergence of new regions and the introduction of powerful beings, such as the Primordials.
