The House of Neberu, also known by their modern sobriquet Fiends, are those who maintained the works of God in Demon: The Fallen. The most distant from humanity, the Fiends spent their time in the heavens knowing when and where everything would happen. One of their number Ahrimal saw that a catastrophe was coming and swore that the angels must act to stop it; instead, their action of acting caused the Rebellion. The Fiends who participated became advisors and strategists, but their abuse of their purpose changed the great design and ended up losing the war. After the Abyss cracked open, the Fiends were horrified to find their once-great creations decaying and damaged without their care; many dedicated themselves to restoring their creations.
The Neberu were the fourth House to come before Adam and Eve.
The curse of the Neberu served as a counterpoint to the foresight they had and sought to teach to humanity. Humans would never remain content with knowing what might be coming; their stability was replaced with worry and longing.
