The Nocten are the closest thing the Moon has to Demons, but they have no drive towards savagery or destruction.
The Nocten are a race of fiendishly inventive creatures, Fae-like beings who's flesh has been replaced by steel, and who live beneath the surface of the Moon and conquer it through force and steel. A heavily ritualistic society, they worship the power of Vesperius and the unstoppable, insatiable order of mechanics.
The beings who would become the Nocten were the original denizens of the moon when it first formed, pale fae who lived in the silvery woods inside the moon's surface. However Vesperius enslaved them, replacing their flesh with metal and warping their minds to be as cruel and crafty as he.
They are the closest things the moon has to Demons, but they are peculiar creatures of the Dark; just as the Lucen have the virtue of Angels but not their sense of civilization and order, the Nocten have the vice of Demons but not their drive to savagery and destruction.
The Nocten are sordidly obsessed with order, rather. Precise mechanics, never-ending clockworks, detailed classifications; they strive to master the untamable nature of the Silver Wilderness through the construction and application of their Shadow Mechanics. As the cycle of the Moon continues, they fight a never-ending battle with the Lucen, oscillating between victory and defeat since the dawn of time. From the Earth below, we simply see this as a cycle; very few people know that when the Moon is dark, the Mechanics have filled most of its insides, or that a Full Moon is caused by the shining roots of the Wilderness inside it.
