Abaddon

Abaddon, the Sineater of Sheol, emerges from the swirling abyss, a behemoth that embodies the darker currents of existence. Everyone sins, and Abaddon can smell it. He cultivates sinners and devours them to sate his hunger. Abaddon is a messy eater. His ultimate goal is to gather enough sin to throw open the gate to Sheol. His physique is a blend of draconic grandeur and lithe lycanthropic grace, standing at an intimidating fifteen feet tall. His scales, as black as the void itself, reflect none of the light around him, creating a sense of perpetual darkness that surrounds his monolithic figure. Amber eyes burn with a fiery intensity, piercing the very essence of those who dare meet his gaze, leaving them exposed under the scrutiny of his otherworldly judgment.

His body is a marvel of terrifying symmetry; muscular arms and legs ending in clawed hands and feet, each movement a study in predatory precision. The lack of visible genitalia speaks to his alien biology, yet the lethal elegance of his tail suggests the presence of unspeakable power. Two recurved horns jut from his skull, like twisted spikes from the darkest depths of a starless night, framing a face that holds a smirk filled with ancient malice. A pair of great, draconic wings complete the ensemble, giving him an air of majesty and power. The red glow of sin emanates from his veins, and crimson sparks arc between his horns.

Abaddon often appears as a charming conversationalist, his words as sharp as his teeth, peppered with sarcasm that cuts deeper than any blade. However, this veneer can vanish in an instant, revealing the cold, calculating predator beneath—ready to feast on the sins, and flesh, of the wicked. Abaddon readily engages in shocking violence, often at mass scale, and will level brutal taunts at his victims while he does so. He is sadistic, and he delights in causing harm to sinners.

Abaddon's primary power is Sinweaving, a versatile ability letting him sense, consume, and manipulate Sin for a variety of effects, including healing and reinforcing the body, firing projectiles, forming constructs, enhancing his cognition, connecting mentally with others, propelled flight, and more. Abaddon's bite peirces any material or barrier, and his roar damages souls. Sin must be gathered from Sinners, beings suffused with negative emotions and dark urges. Abaddon does not produce sin, he must consume it. Abaddon is composed entirely of Sin, and can starve if he goes too long without eating, slowly weakening until sated. Abaddon can't die, if his body is destroyed it leaves behind an orb of concentrated sin which drips with blood continuously. When this sinful blood accumulates in sufficient amounts Abaddon will emerge from the liquid with a brand new body.

Abaddon tends towards violence and delights in tearing mortals apart. As a creature of the hive mind, Abaddon shares a collective consciousness with his kin, yet retains his individuality, allowing for a nuanced interplay of personalities. He and his kin hail from Sheol, a dimension of blood and viscera held together by sin. Sheol houses 'Proto Abaddon', the template all others are based upon, as well as 9 Primes, kaiju sized Abaddon instances which stand at over a mile tall each. When sufficient sin has been gathered Abaddon will use it to open the gate to Sheol and invite a Prime into reality, plunging the entire world into blood and death.

Abaddon ultimately aims to facilitate the consumption of the world by Sheol, and will happily cultivate sinners if he feels it will accelerate the proccess. He will sometimes turn a worthy sinner into a Sinweaver, giving them access to sinweaving. When a sinweaver gathers enough sin they will transform into a new sineater, a freshly born Abaddon instance. Siring a sinweaver is private and intimately sexual, Abaddon drains the blood of the prospective sinweaver, then feeds them with his own sin. The process binds the two forever in blood and purpose, and Abaddon will teach the sinweaver for 2~ish years before turning them loose on the world.
