Mycorjet

Ruling from the 222nd level of the Abyss, Arnon functions as queen of all fungus, spores, and mold. She lives in a palace built out of twelve separate mushrooms, each several miles high, and connected by bridges of fine woven mycelium hairs. Arnon was summoned to the material plane by the immortal Opmac during the Second Age. Opmac coerced Arnon to help him conquer the Korillian city of Dawn in exchange for freeing her from the Abyss. Opmac empowered her to infect as many subjects with her fungus as she could, as long as her army served his needs.
Arnon is described as a beautiful humanoid female with graceful features and an intoxicating aura of spores that, if inhaled, makes one into an infatuated devotee. She uses her beauty, spore cloud, and natural charisma to draw followers to her side, helping her to spread her vision of covering the material plane in fungus. Though Arnon is incredibly powerful, she is also calculating, willing to serve more powerful forces if it means her agenda is ultimately furthered. Her beauty and intelligence allow her to slowly ingratiate herself with her oppressors, gradually warping their minds. Like her disease corrupts the living, her sexual presence twists the resolve of anyone foolish enough to try to control her.
Arnon is served by her first lieutenant The Demon Yibiyru. The Lady of Pain serves her master by enacting the fungal queen's desires to inflict a slow and terrifying death on all the living. Yibiyru can change her form at will so she can ingratiate herself into a town or civilization. From there, the demoness begins developing potential "talent" that could be manipulated into transforming into thralls, in exchange for powers. After undergoing the grotesque Feast of Flesh, the thralls emerge warped and twisted, infecting everything they touch with Arnon's Madness - Disease.
The fungus queen's ultimate goal is to take over the material plane by infecting the population with her disease, turning them into a hive mind that serves only her. She intends to transfer her fungal kingdom from the Abyss to the surface world, covering everything in her mold and spores. The fungal queen is able to communicate with her troops through her network of mycelium roots and can transport herself instantaneously through her labyrinth of fungus. Often referred to as Shedaklah, Mycorji, or Mycorjet, Arnon's kingdom is a single living organism; Arnon, her castle, her army and world of fungus all living together in one Mycorjet or "paradise."
