A German legend that might fascinate you:
The Erl-King (also known as The Erkling or Erlkönig).
He is a sinister elf like forest spirit.
He is a vicious lord of the faeries who stalks children that stay in the woods for too long, and kills them by a single touch. Some people depict him as having stag antlers growing out of his head.
Erlkönig is German for "The Alder King" and may in turn be an 18th-century mistranslation of the original Danish word "Ellerkonge".
He appeared in a spooky poem written by Johann Wolfgang von Goethe.
A minor fact, but some people think the Erl-King is Herne the Hunter, Master of the Wild Hunt. It's probable.
Yes but the Erlkönig is a one Poem only thing. We dont really have wide spread legends for him. (I got chewd out by me literatur teacher for that one). He may have a following, but all in all Göthe basicly invented him. We do have a migical King for the gnomes and dwarf´s, or all the earths elementals in generel and that is Meister Schraat, comonly known as Rübezahl.
Some German myths, stories, and folktales feature elves.
If one is to hear strange music coming from underneath hills or woods that appear uninhabited, chances are that area is inhabited by elves.
When walking through the woods, one should pay very special attention to hills close to streams or ringed with thorns. Walking around such a hill, one might notice places where the ground is sunken. Travelers should beware of these hollow hills, as they are likely to be the homes of elves.
Also, watch out for stray sods. Sometimes elves will enchant the grass around their mounds to cause travelers to lose their bearings and force them to go the other direction. One way to do this is to place stray sods around their mounds.
