There will be mages willing to bargain with the ink demons. Either promise a few magical writings with intentional typos in return for freedom from interference with their real work, or payment for interference with their rivals or enemies.Typos in magical writing allow for entities from a reality of misinformation to invade. They are called ink demons but have nothing to do with the Pit. Rather they try to trick more casters to add typos to their magical writing and allow more of their kind to invade. So far that is all that they do.
Someone will find a use for this moss and will pay those who grow it.One species of moss reproduces by transforming hair. Anyone who touches it has their hair converted into the moss. Shaving it doesn't help, only cold conditions for more than a month will revert the effect.
