This subgenre may mix with any other subgenre except comic 
fantasy. Very few works mix dark fantasy with high fantasy 
but this might happen: Memory, Sorrow, and Thorn is the 
best example. Most of the time, dark fantasy mixes with 
urban fantasy. That's what can be called "urban dark 
fantasy". In horror, if elements from the story are 
mythological or from fairy tales, it will be dark fantasy. 
Horror tales' rewritings are also considered fairytale 
fantasy.
