Horror

"All I wanted was to break the secrets. I didn't think it would grow and become this...parasite."

- Ekipi expressing her regret at the creation of the Dark Arts and the birth of the Horrors Horror (霊無き (ホラー), Horā lit. Soulless) refers to creatures and humans who have been devoured by the Dark Arts or have entered the Dark World (闇の世界, Yami no Sekai), the source of all the "darkness" produced by the Dark Arts. Horrors come in different forms and classifications, and the first Horror and creator of the Dark Arts is Ekipi, who effectively governs and rules all of the Horrors and the Dark World.

Trivia

 * As one could tell, Horrors are heavily inspired by Lovecraftian lore and Cthulhu mythos, most prominently the madness and deformation of its victims.
