Dullahans (デュラハン) are a race of undead from YGGDRASIL.


Dullahans are a headless corpse that carries its decapitated head. They can vary from chalk-white skin to rotting flesh. While normally seen carrying their heads, some Dullahan can attach their heads back to their necks by way of a ribbon or choker or collar; a preferable way for a player with Dullahan avatars.


A Dullahan is similar to an animated corpse like a zombie; but unlike zombies, Dullahan are immune to decapitation because of their detachable heads.[1] Being an undead, they are also immune to poison and negative energy.[2]
