The location shares its name with a 120m tall rock on the eastern bank of the Rhine near St. Goarshausen, and seems to be based on this place. Lorelei is also the name of a mermaid who lured unwary fisherman to their death by singing the most beautiful song they had ever heard.
It seems that the buildings and the grounds on this area belongs to the Douglas family, as Helena takes residence here.
Lorelei is on on the very top of the mountain. All fights start at the top of the building, and fighters can be thrown down it during the match. This stage is only playable at night.
In Dead or Alive 5 Ultimate it is given a Halloween theme. The stage is decorated with jack-o'-lanterns and a red full moon is visible in the background. In addition, the very lowest level has banners of Volf, a Greater Fiend and enemy boss in Ninja Gaiden II (2008). Both Volf's Castle and Lorelei have similar gothic design schemes, though Lorelei is much smaller. The original variation of the stage is featured in Dead or Alive 5 Ultimate Arcade and will be available in an update for the console version.
