The elderly and powerful wizard John Smelkor, on a trip to one of the tropical islands on the Banhoesea/Kraken Confederacy border to speak with a Kraken, contracted a heat rash which turned into a bad case of jock itch. Scratching only spread the problem. Rather then use potions or ungents to get rid of it, the irritated mage used magic to wrench it out of his skin.
The magic accidently animated the jock itch fungus and gave it sentiment, and turned it into a very thin handkercheif sized creature a few cells thick. It fled from the mage’s sight and hid in corners, feeding on small insects and spiders which it coiled around and like a vampire, sucked dry. It was not averse to feeding on certain of the mage’s guests during the night.
Of course it was far too small to suck a human dry, but it did drain small amounts of blood and seed itself into the wounds, leaving them infected with itchy fungus.The guests would wake, scratch hard, and then think that they had injured themselves through scratching.It never targeted the mage that it had come from, seeing him as a father.
The fungus has the intelligence of a little puppy. It cannot speak as it has no mouth or vocal cords but can manipulate small and light objects. It generally will not even show itself to humans who are awake unless they attack it’s master, when it will come out from under the floorboards to defend him.
Because it is so thin, weapons will have very little impact on it. If cut, even if shredded, the strips will heal up.If on the body any attempt to cut or otherwise harm it will probebly hurt the person.who’s body it is in. Fire will destroy it however, as will acids and certain creams. Whatever it touches, be they wounds or anythiing else, will be dusted with spores that might or might not sprout later into normal jock itch fungus in the right conditions.
