Fabled Erelhei
From DQWiki
also known as Sunken Erelhei.
A now sunken landmass several thousand miles to the west of central Terranova and just north of the equator. Original home of the Erelheine after leaving Arcadia.
A disaster claimed most of Erelhei around two thousand years ago, causing it to sink below the waves. Survivors of the disaster fled westwards in a great fleet, and settled in Kinlu and the Dragon Isles.
The area once occupied by Erelhei is said to be haunted by the spirits of the dead, and home to many dangers. There are also numerous mundane risks in the treacherous rocks and reefs.
Occasionally brave or foolhardy folk have ventured to Erelhei in the hope of retrieving valuable salvage; few have been heard from again.
