In anime and light novel, Sword Art Online, setting for the second arc is based on Álfheimr, referred to as Alfheim.
Aerdrie's realm, a floating palace called the Aerie, shifts across the border between Arborea and Ysgard; sometimes it is found in Arvandor and sometimes in Alfheim.
Nór's new kingdom is now said to have been what is south-eastern Norway today, as it extended from Jötunheim mountains in the north to what was later known as Álfheim (roughly the modern Swedish Bohuslän) in the south, the southern border of Nór's land being what is now the Glomma river whose southwestern course is not very far inside the southeastern border of modern Norway.
