Abhorrent Overlord

The plane of Theros, disconnected as it is from the larger multiverse, has none of the traditional demons and devils birthed from the Abyss or the Nine Hells. Instead, the demons of Theros are the corrupted souls of dead mortals, twisted by hatred and negative emotions. When the darkest of mortal souls die, they are imprisoned in a special area of the Underworld known as Tartarus, as far from the blessed starlight of Nyx as possible.   After a time, these souls are wrapped by the intensity of their punishment, transforming them into demons. Once this happens, they sometimes find ways to escape their prison, leaving the Underworld and returning once more to the mortal realm. The shapes and forms these demons take are almost always reminiscent of the wrongs they committed while alive, a never-ending reminder of the sins for which they are to be punished.   Man-eating Monster The abhorrent overlord are demons with large, leathery wings, feet that have fused into bird-like toes, and fingers tipped with sharply-curved claws. This appearance signifies the connection the abhorrent overlord shares with the monstrous, flesh-eating harpies. In its mortal life the overlord, like the harpies, fed on human flesh to sustain itself. This foul act doomed the overlord, condemning it to an afterlife in the Underworld prison, Tartarus.   Once there, the overlord's punishment warped it, transforming it into a beast the must feed on the life force of others to sate its hunger. In Tartarus, these demons will attack and fruitlessly attempt to devour other prisoners, whose corrupt souls provide them with no noursihment. As time goes on, they will begin to starve and waste away, turning to skin and bone, but unable to die as a result of their suffering. Once an abhorrent overlord escapes back to the mortal realm, its first act will be to feed relentlessly on living mortal,s until it has gorged itself to bursting.   Scourge of the Skies The abhoent overlord's connection to the bird-like harpies is much more than skin deep. Harpies are naturally drawn to the presence of an abhorrent overlord, where the will feed on the carrin corpses left behind by the demon after it has eaten its fill.   The name of these demons, overlord, was even given to them by mortals for their ability to summon and command harpies in battle. Just as harpies do, the aborrent overlord has a powerful singing voice; but unlike the harpies, the overlord's voice is disgusting and repuluve to mortals, instead acting as unresistable lure for harpies. Just as a harpy can sing and charm a mortal into doing its bidding, an abhorrent overlord can sing and charm any number of harpies into acting under its orders.
