Red Ruth, a night hag of ancient and malevolent lineage, resides in the thorny forests of Avernus, the first layer of Hell. Her skin, a deep shade of purple, is marred by warts and stretched tightly over her skeletal frame, accentuating her long, hooked nose. Her eyes, glowing with a fiendish delight, peer out from beneath a tangled mess of gray hair. Clad in tattered red robes that flutter ominously around her, Red Ruth adorns her waist with a belt from which hang the skulls of her victims, each one a testament to her cruel reign over this forsaken land. Her grin, wide and filled with sharp, yellowed teeth, is a constant reminder of her delight in the suffering of others.

In her shack, constructed from the bones of the damned and surrounded by a forest of thorns, Red Ruth plots her schemes. Her intelligence is as sharp as the thorns that encircle her home, and she uses it to manipulate and torment the souls unfortunate enough to cross her path. Her unique quirk is her habit of humming a haunting melody as she works, a tune that seems to resonate with the despair of Avernus itself.

Red Ruth's desire is to ascend in the infernal hierarchy, to gain more power and control over the souls that wander the planes. However, her path is blocked by the constant battles and betrayals that define the politics of Hell. Undeterred, she uses her cunning to forge pacts with lesser demons, promising them power in exchange for their loyalty. This strategy works because in the chaotic realm of Avernus, alliances are fleeting, and the promise of power is often enough to sway the weak-minded.

Yet, her life is fraught with conflict. Other hags and demons vie for the same power, and the ever-shifting alliances mean that today's ally could be tomorrow's enemy. Despite these challenges, Red Ruth remains steadfast in her pursuit of dominance, her evil nature driving her to ever greater acts of cruelty and manipulation. Her story is one of relentless ambition in a world where the only constant is betrayal, and her end, should it ever come, will be as brutal and unforgiving as the life she has led.
