He holds up a hand, "I'm... fine..." wheeze.
GLADIOLA kens, and doesn't get a clear picture. There is nocker glamour and cantrips all over, but the goop that Briar is tucking into is clearly chimerical and nasty.
What else she can tell, is that the goop is likely noxious and poisonous, but Briar seems unaffected. However, Art seems to be showing some signs that lead not towards issues with the current air quality, but of poisoning. Something about his color, the way his pupils have dilated. Madern too, but to a lesser extent.
THISTLE can pick through the glamour easily. After all, it's mostly hers! That sludge is nasty, but intriguing. Definitely worth a sample, which she gets. However, there is more glamour within the crucible still remaining. It feels... different! A glowing light, warm and pure against the smoke and sludge, starts to trickle through the cracks. A stirring within the Crucible, whatever it is cannot get free through the cracks.
