Dullahans

The Dullahan is a supernatural entity, spawned almost at random after the beheading of a human on a battlefield or during a tragic event. They are quite literally headless horsemen, often found on horseback and missing their head entirely. Most Dullahans lack their head, but some still have them, wearing them almost like a hat or carrying them around.

Dullahans often terrorize human populations, chasing them down and killing them. Very rarely does a Dullahan live alongside humans, and when they do they often hunt other supernatural entities to avoid turning into their darker bretheren. Dullahans are also known to be relentless when they've chosen a victim, going through hell or high water to hunt down their target and slaughter them without mercy. This has given them the nickname of 'Death's Herald', as death isn't far behind if you're marked by a Dullahan.

Dullahans bear an intense fear of gold. The mere sight of gold is enough to bother them, and the touch of it will burn them. Gold weapons or bullets are often used to kill Dullahans, and gold objects can drive them off if used against them. If the Dullahan still has its head, its head can be destroyed to kill the Dullahan. The head is weak to most forms of damage, just like a human's. Magic can also be used to stop a Dullahan in its tracks or repell it.
