Demons were malevolent fiends native to the Lower Realms, ever-evolving engines of destruction spawned to act as living instruments of oblivion. They were personifications of ferocity and elemental devastation, existing to further the tendency of all things to slide into entropy and ruin. Demons varied widely in appearance and abilities, from towering, horned creatures with leathery wings to serpentine fiends dripping with venom. Barely contained by their monstrous forms, demons were creatures of raw physicality and rage, the embodiment of malignant chaos.
They thrived on pain, suffering, and the corruption of mortal souls, often working to sow discord and spread chaos wherever they roamed. Encounters with demons were perilous, as their mere presence could warp reality and fill the air with an aura of dread. Some demons could summon lesser creatures from the Lower Planes to do their bidding, while others wielded deadly magic or wielded weapons forged from infernal metals.
Demons were often depicted as the sworn enemies of gods and mortal races alike, their insatiable hunger for power driving them to manipulate mortals into dark pacts and sinister bargains. Their schemes spanned across planes of existence, threatening entire civilizations with their malevolent influence. Adventurers who faced demons knew that victory often came at great cost, requiring courage, cunning, and sometimes sacrifices to banish or destroy these embodiments of pure evil.
