The Stone Tent

Oh, now THAT is a funny story. so you see...

— Jasper Cameron, Leader of The Bronze Ravens

There we were, helping out... I believe it was Mertyl Redwyrm. Our goal was twofold. We were to slay the gorgon that had been spotted in the area, but Mertyl also wanted to confirm the presence of a magical inversion field. A rather rare wild magic phenomenon that does exactly what is sounds like, inverts the magical properties of any magics that pass through it. Healing potions instead inflict grievous wounds on a person, flaming swords become fireproof, objects that emit light instead absorb it, you know, that sort of thing. But first and foremost was dealing with the gorgon.
Well, of course, knowing that we were dealing with a gorgon, we had stocked up on the necessary precautions, including several potions of stone-to-flesh. What? No you don't drink them, have you ever seen a statue drink? Actually, don't answer that, you probably have with how long you've stuck around. So anyway, stone-to-flesh potion are usually sprayed or rubbed over a person, and similar to a gorgon slowly reverse the petrification process. Start with the head, trust me on that one.
So there we are, a myself and a few ravens along with good old Mertyl. Minding our own business, when our scout cries out a warning and next thing we know the gorgon is ramming our supply cart, trying its best to gore us or our horses. Turns around and kicks the cart again, knocking the whole thing over, before breathing out its petrifying breath over Mertyl, who had been knocked to the ground in the commotion.
Jeb was taken less by surprise than the rest of us, and managed to bring his great axe down on one of the creatures hind legs, hobbling it, and from there it was short work for the rest of us to finish the monster off. Once that we done we took stock of our situation, only to fins that poor Mertyl had been well and truly blasted by the beasts breath and was turning to stone. Not only that, but when the beast had rammed out cart, it had broken open a good chunk of our supplies, to include our potions. What? No, you should almost never carry potions on you in battle, glass has a tendency to shatter and then what good would they do. Unless you have a magically durable case or some extra-dimensional pocket they are best left with your other traveling supplies.
Well, we had a big canopy style tent, so that Mertyl could do her work than the potions had spilled over in the ruckus. Figured we could send a few folks back to the city to get more and the rest of us would keep the soon to be stone Mertyl safe until they returned. So we went about setting up the canopy and getting camp ready for the night. The next morning, wouldn't you know it, I wake up to Mertyl swearing up a storm worthy of any sailor (which I won't repeat here) asking what we had done to her tent and her notes.
Turns out, at some point during the night that inversion field had passed through the camp. A wonderful twist of fate, as we didn't have to wait for the folks we sent to town to come back with more potions. However, everything that the potions had soaked into, from our cart and Mertyl's books, to the formerly cloth canopy, had turned into solid stone. There were obviously a couple of other things that the inversion field had effects on, but we will leave those for another time.
