For an evil organization in a story, there are several great names. 'The Doom Brigade' is a good one. It implies that they bring doom wherever they go. 'The Abyssal Cabal' is also a great choice as 'abyssal' often connotes something dark and deep, like the abyss, and 'cabal' gives the idea of a secretive, plotting group. 'The Hellfire Legion' is another option. The word 'hellfire' is associated with destruction and evil, and 'legion' makes it seem like a large and powerful group of villains.
Some possible names could be 'The Dark Covenant', 'The Shadow Syndicate' or 'The Malevolent Order'.
How about 'The Nightmare Collective'? It gives the feeling that they are the source of nightmares. Or 'The Death's Grasp Society', which sounds really spooky. Another name could be 'The Macabre Mafia'.
I don't know which novel has an organization called the Fiendish Wind. However, Fiendish Wind was a common name for a character in web novels. There were probably many novels that had this character. Can you provide more background information or the title of the novel? This way, I can better answer your questions.
Lilith. In many mythologies, Lilith is seen as a dark and somewhat malevolent figure, so it would be a great evil name for a story.
Raven. Ravens are often associated with death and darkness in many cultures. Using it as a name can bring an air of mystery and evil to a story. For example, a character named Raven could be a brooding villain who lurks in the shadows.
Morgoth. It is a name from Tolkien's legendarium, representing a great and evil power.
One great 'evil organization' light novel is 'Overlord'. In this novel, the protagonist finds himself in a game world where he becomes an all - powerful undead ruler of an 'evil' organization of sorts. Another is 'Re:Zero − Starting Life in Another World'. While not strictly about an 'evil organization' at first glance, there are groups with their own self - serving and often immoral agendas. 'No Game No Life' also features a world where the main characters face off against an established order that could be considered an 'evil organization' in some ways.
Well, there's Mordred. In Arthurian legends, Mordred was a very devious character. Also, Cain is a name that brings to mind the first murderer in the Bible, so it can be considered an evil name for a story. And Vlad, as in Vlad the Impaler, who was known for his extreme cruelty.
You could consider names like 'The Dark Lord', 'Malice Master', or 'Sinister Soul'.
One fictional research organization name is Stark Industries in the Iron Man series. While mainly an industrial company, it also conducts a lot of high - tech research. Then there's the Initiative from the Buffy the Vampire Slayer universe. It was a government - funded research organization that studied the supernatural. In the world of Jurassic Park, InGen is a famous research organization. They were involved in genetic research to clone dinosaurs, which led to many dangerous situations.
Bellatrix. This name has been made famous by the 'Harry Potter' series as the name of a very evil witch. It has a certain elegance combined with a sense of danger and evil, which can be very appealing for a story's antagonist.
