Aetgard is a large region of western Arad, spanning from the north coast down to the dread Fey Forest in the south which separates it from the Karnath region. It is now more commonly referred to as the Lost Lands, after the massive loss of human life resulting from the Aetgardian Plague that swept through the region, followed by outbreaks of nether-corruption, resen infestation, and an ever-growing population of canim. The area is now under Quarantine.
See the Lost Lands article for more information.
Not to be confused with the kingdom of the same name.
