The tiefling’s minions hold down the town’s priest as she savagely scalps him, washing his face in red blood—only the beginning of his torment, the path to corruption before her infernal allies claim his soul.
Like a fool his merchant quarry pursues the allure of the incubus out of the tavern, the simple minds of the bodyguards distracted by will-o’-wisps. Before any defender’s sword can react to the dying trader’s screams the dwarf and his abyssal servant are long gone.
As their companions contemplate how to cross the chasm they simply sling out a rope and call out to Beyond, things from the void swiftly carrying them aloft and across the expanse.
Diabolists are not typical mages or priests, devoting themselves not to study or prayer, only to finding and taking the fastest pursuits to power—through dark pacts with evil creatures hungering for the foolish souls of bargainers. These greedy and despicable individuals wager their very souls to make bargains with not just one creature from beyond the Material Plane but many entities, calling on the malevolent powers to do their bidding. Any and all dark arts are the purview of diabolists and there is no depth to which they will not sink as they seek to conjure ever more powerful allies. The deals one must strike in order to summon evil entities with a whim are dire indeed however, and the further along the corrupted path one travels the greater one finds the demands of their otherworldly partners.
The path of the diabolist is rarely lauded or promoted within society and the very nature of their art requires one to have a taste for taboo. Only the strong of will and spirit can endure the trials required to learn the secrets of diabolism, and though master summoners frequently take on many apprentices most of these deluded fools are merely pawns used for sacrifice. Devious, foul, and wily as they might be, diabolists are always keen to acquire relics, tokens of power, or forbidden lore whenever the opportunity arises and they can be trusted to do whatever they must in their relentless pursuits.
Greed is what inspires most diabolists to take up the darkest arts of conjuration but they are never sated—the need for more power and wealth drives them ever forward the further they fall toward depravity in a vicious cycle that ends in eternal torment. The aid of demons and devils does not come without a cost however and either divine relics, great treasures, or the souls of the living must be sacrificed in order for diabolists to forge new unholy alliances.
