No, that's not Dusty.
I think it something within the mushroom... it's living, after all.
Or one of his experiments.
Here's an idea...
A lovely discussion between Master Neloth and Divayth Fyr...
Sometimes, I wish there was just a random quest where Divayth Fyr just shows up out of nowhere and crap happens... It would be such an interesting thing to watch.
While I'm actually a Hermaeus Mora fangirl myself, I'd like to sign in as an avid Neloth enthusiast and tip my hat to his fangirls and boys, because he deserves all the love he can get. Not only does he have excellent taste in tea, but every word that falls out of his mouth is also pure, snarky gold.
