Dark fantasy is a subgenre of fantasy literature that blends elements of traditional fantasy with darker, more sinister, and often macabre themes. It incorporates elements of horror, gothic fiction, and the supernatural to create a more ominous and unsettling atmosphere. Here are some key characteristics of dark fantasy:

Dark and Atmospheric:
Dark fantasy is characterized by its dark and brooding atmosphere. It often features grim, eerie, or gothic settings that evoke a sense of foreboding and unease.

Moral Ambiguity:
Dark fantasy frequently explores moral ambiguity, blurring the lines between good and evil. Characters may have complex, morally ambiguous motivations, and the distinction between heroes and villains can be unclear.

Horror Elements:
Dark fantasy often includes horror elements, such as supernatural creatures, dark magic, and themes of death and decay. The genre can be unsettling and may incorporate elements of fear, dread, and the macabre.

Antiheroes:
Protagonists in dark fantasy are often antiheroes, flawed and morally gray characters who do what is necessary to survive or achieve their goals, even if it means making morally questionable choices.

Bleak Endings:
Dark fantasy stories may not have traditional "happily ever after" endings. Instead, they often conclude with a sense of ambiguity or even tragedy, leaving readers with a lingering sense of darkness.

Supernatural Elements:
Dark fantasy commonly features supernatural or paranormal elements, such as ghosts, vampires, demons, and other creatures of the night. These elements contribute to the eerie and unsettling tone.

Exploration of Taboos:
The genre may explore taboo subjects and dark themes, including violence, addiction, madness, and the macabre, often in ways that challenge social norms.

Notable examples of dark fantasy include Clive Barker's "Books of Blood" series, Neil Gaiman's "The Sandman" graphic novel series, and Michael Moorcock's "Elric of Melniboné" series. Dark fantasy offers a subversive and often thought-provoking take on traditional fantasy, embracing the darker aspects of human nature and the supernatural to create stories that are both haunting and captivating.
