Nightfall (event)

Nightfall is the prophesised event in which the Realm of Torment will seep into the mortal world. Events related to nightfall include areas of the world being replaced by Realm of Torment equivalents, Demons appearing in the world, and the imprisoned god Abaddon being released.

Nightfall begins at the end of the Dasha Vestibule or Dzagonur Bastion mission, although it may have begun much earlier in the Tomb of the Primeval Kings. Areas of Elona are replaced by realm of torment areas after the Grand Court of Sebelkeh Mission, and nightfall is said to fully come to Elona after Varesh Ossa is killed in the Ruins of Morah mission.
