Generate a highly detailed surreal horror fantasy image of a monstrous embodiment of the plague. The creature should be an amalgamation of nightmarish elements: a grotesque, shifting form with writhing tendrils, festering sores, and an aura of miasma. Its skin should appear diseased and decaying, with pustules and oozing wounds. Surround the monster with eerie, distorted landscapes that reflect the plague's corrupting influence, such as crumbling buildings, twisted, barren trees, and swirling, toxic fog. The overall scene should evoke a sense of dread and otherworldly horror.
