Dark Magic is a form of magic used by sorcerers with evil intentions, for sinister purposes. Although magic itself is basically neutral, its morality is determined by how it is used and what are the motives behind the actions of a sorcerer.
However, there are some applications of magic and some spells which are used only with the purpose of doing evil or inflicting harm upon someone.
Witches and warlocks very powerful as Morgana are very skilled in this field of magic.
The main applications are:
- The use of poppets to inflict pain on the person that the doll represents (The Dragon's Call).
- The creation of an Afanc with the plague this creature's venom produces (The Mark of Nimueh).
- Necromancy (Excalibur, The Sins of the Father, The Fires of Idirsholas, The Tears of Uther Pendragon: Part Two, Lancelot du Lac).
- Enchanting a mandrake root to traumatize the spell's victim with hallucinations (The Tears of Uther Pendragon).
- The ability of possessing someone (The Curse of Cornelius Sigan, Goblin's Gold, The Changeling, A Herald of the New Age).
- The curse by which a sorcerer can transform someone into a Bastet (The Lady of the Lake).
- The use of a Phoenix Eye, binding it to a person's likeness (The Eye of the Phoenix).
- The Cup ritual that can give someone immortality (The Coming of Arthur: Part One).
- The blood sacrifice performed by the High Priestesses of the Old Religion to release the Dorocha (The Darkest Hour: Part One).
- The enchantment Morgana cast on her pendant, binding it to the left hand path, so that it would counteract any healing magic (The Wicked Day).
- The Fomorroh, used by the High Priestesses to enslave their enemies' minds (A Servant of Two Masters).
- The mental torture used by the Catha (The Secret Sharer).
- Morgana's magical coin (Lancelot du Lac).
- The pentacle for necromancy, used by Merlin (Lancelot du Lac).
- The use of a Nathair, a serpent used by High Priestesses that causes pain beyond any imagination (The Sword in the Stone: Part One).
- Merlin's curse on a poppet that represented Morgana and consumed her powers, leaving her unable to use magic (The Sword in the Stone: Part Two).
- The conjuring of magical and poisonous snakes with which a sorcerer can implant horrible visions in the mind of those who get bitten (The Dark Tower).
- The ancient ritual of the "Teine Diaga", the "sacred fire", which used the mandrake root to bring unimaginable terror to the victim (their screams could be heard twenty leagues away). When it was finally over, their will was no longer their own, they were slaves of the High Priestesses for eternity (The Dark Tower).
- The Ragaid, a dark spell which caused the skin to grow across the victim's face until he suffocated (The Kindness of Strangers).
- The use of a Gean Canach, magical creature similar to an enormous slug, fearsome for those who have magic. It was forged by the tears of the Earth Mother Nemaine and it devours the magic of others, draining them of their power (The Diamond of the Day: Part One).
