According to medieval Germanic -speaking cultures, elves generally seem to have been thought of as beings with magical powers and supernatural beauty, ambivalent towards everyday people and capable of either helping or hindering them.
Here's the Queen of elves.
This queen has pale skin - typical for this kind of creatures - this color symbolizes purity and honor.
Her white long hair symbolizes her wisdom and experience of being a queen that had to protect her successors.
Queen’s sparkling eyes give her supervision- she recognizes an enemy straightaway.
Her outfit combines two incompatible states- soft, light feathers on her shoulders and impenetrable, heavy armor. Colors of her clothing also have meaning- black shows tragedy she has had in her life, whereas reflects her majesty.
There’s a skull on the armor- it gives
a hint to others that this queen would not be won that easy.
