An ancient swamp hag emerging from a mist-filled forest, gaunt skeletal female figure with decayed gray skin, deep wrinkles, glowing eyes, crooked broken teeth visible through a twisted snarl. Long stringy white hair tangled and damp beneath a tattered dark hood. Thin bony hands with elongated fingers and cracked nails reaching forward in a predatory pose. Wears layered, rotting cloth robes stitched together from burlap, leather scraps, talismans, and bone charms. Her body posture is hunched and animalistic, conveying hunger and menace. Environment is a foggy marsh forest with twisted dead trees, cold blue-gray mist, damp ground, and silhouettes of other shapes lurking behind. Lighting is low-key and eerie with cool tones, heavy atmosphere, high contrast, cinematic horror fantasy illustration, extremely detailed textures, sharp focus, gritty dark fantasy mood
