A fiend was a malevolent and infernal type of creature that originated from the Lower Realms. These beings were embodiments of pure evil, driven by a relentless desire to corrupt, destroy, and dominate all that was good and just. In appearance, fiends varied greatly, reflecting the chaotic and corrupt nature of their origins, but many possessed claws, wings, or horns. Their skin ranged from fiery reds and ashen grays to oily blacks, often marked with infernal runes or scars.
Fiends typically inhabited the hellish realms of their creation, where they schemed and vied for power among their infernal kin. However, they were often summoned to the material plane by dark rituals, seeking to spread their malevolence and fulfill the sinister bargains they struck with mortals. Their presence in the Material Realm was a harbinger of doom and despair, as they delighted in causing suffering and chaos.
