A colored drawing of Ylszaerogg's mortal form that the Goddess of the Zeirim and the dark realm of Gholghannoir takes when she emerges into the material plane.

Ylszaerogg is a major character in my graphic novel series Fablefold, and is an ancient deity known as a Withered One, a creature ascended to godhood through the death of a planet. She is a god of desire and terror, pain and pleasure intertwined, who rules over the world beneath The Narrative known as Golghannoir. Her archenemy is the 30-winged god of the heavenly realm of Sayonart, Lord Ziv, who created the anthromorphic Arkborne from part of her essence after she was defeated in an ancient war and sealed away. Left in a fallen state in Golghannoir, she is it's ruler, and created the Zeirim with her husband Tszorath. After creating the 72 Arch Zeirim, which were forefathers to the others, she and Tszorath lay with one another and she gave birth to her two sons Saetyraan and Tiesaraiel, and named them Princes of Golghannoir. Although Tiesaraiel is more wanderlust in his endeavors for their kingdom, her son Saetyraan is her personal champion, having trained him in how to fight and use his innate Zeirim magic, and the two of them share a consensual and incestuous relationship with one another.

She towers over most creatures at being nearly 20 feet tall in her true form, not counting her long horns, has two long sinuous tails with blades on the tips, and has six arms and breasts.

In her mortal form, despite her power level being a shade of what it once was, she is still a fearsome adversary and perhaps one of the most powerful beings in the FableFold universe. Being as dangerous as she is, she can barely contain her power levels and thus, her mortal form is of a 12-ft tall pitch black Oryx Arkborne. Although she is renowned for being a powerful sorceress and the origin of dark magic, she is just as deadly with her fists and claws and savors the thrill of close combat, pummeling foes and overwhelming them with shadow-endowed fists, elbow strikes and headbutts.
