Accursed Succubus
Creature 5Succubi are manifestations of the sin of destructive lust, and they are the most attractive of all demons-as befits their role in seducing mortals to fall to sin. The concept of gender is fluid to a succubus, as they can adopt countless humanoid forms of any gender to aid in their goals. Most succubi have a feminine true form (incubi, which usually have a masculine true form, are a different kind of demon), but regardless of gender, a lust demon is supernaturally beautiful or handsome, but with curving horns, bat wings, sharp claws, and a sinuous tail.
When disguised as a mortal humanoid on the Material Plane, a succubus whispers into the ears of mortals, urging them to pursue their darkest and most destructive desires and pushing them into depravity, using magic only if persuasion fails. While mortals often fixate on succubi's application of sexual lust, these demons are can easily exploit lust for power, knowledge, fame, or any other desire as easily as more carnal appetites. Their ability to infiltrate societies makes them excellent spies, assassins, and political saboteurs as well. Ultimately, the succubus enjoys all means of upending mortal culture.
When a sinful mortal soul is judged and sent on to the Abyss, it can become a deadly fiend-a demon. Demons are living incarnations of sin-be they classic sins like wrath or gluttony, or more "specialized" depravities like an obsession with torture or the act of treason or treachery. Once formed, a demon's driving goals are twofold-the amassing of personal power, and the corruption of mortal souls to cause them to become tainted by sin. In this way demons ensure a never-ending supply of new demons to bolster their ever-growing ranks in the Abyss.
