Demon Queen of Fungi

Zuggtmoy is the Demon Queen of Fungi, but not considered a true patron of fungi. She was merely the embodiment of the death and virulence that fungi represented, and fully willing to subvert the natural order for her own ends. The Lady of Rot and Decay did not use decomposition for the higher purposes of renewal or rebirth, desiring destruction purely for its own sake.
 
She has not humanoid form but can roughly mold herself into one. She is utterly alien in body and mind, her only intrest in humanoid creatures is to infect them with her spores. Upon doing this they become mindless slaves.
 
Not only this but she delights in deception and treachery. She loves the slow rot from inside.
