He casts a Detect Magic and watches.

Blessed are they who happen to be standing near Blai.

Thall has to recast his Detect Magic, but only once. Blai's Bless lasts just over seven minutes.

"Which is what you'd expect in a new fourth circle."

"Right. Maybe it's... single-target spells versus spells that target a lot of people? But that's just a guess."

"Or the circle or the school - only your summonses were affected, right?"

"As far as I can tell, yeah. I think Delay Poison might technically be a healing spell but I don't remember for sure, and most healing spells can't really last longer or shorter..."

"Most things like Cures and Remove Blindness and such don't have a duration that could extend."

Nod.

...Blai may notice, at this point, that Hulrun has returned and is keeping a much closer eye on Thall than before, though he's still standing about six paces back.

He HASN'T ESCAPED he is RIGHT THERE

Hulrun does not seem particularly interested in clarifying why, exactly, he's looking at Thall.

Well, he can look. He is authorized to look.

Hey Chief, Anevia's got a message for you. You see that woman in the hood sitting at the end of that table?

He gestures subtly at the person he's indicating.

I see her.

Well, whoever she is, she's a stranger — Irabeth's never seen her before. But get this, she's got some kind of illusion up, and she's wearing some magic items! She's been steering clear of the inquisitors, not that I can blame her, and to top it all off she's been asking all kinds of suspicious questions about what happened in the Gray Garrison.

Does Anevia want me to talk to her or steer clear or ask the Prelate to investigate?

Depends, do you have any Protection from Evil going spare? She doesn't read Evil, but she might have an Undetectable Alignment up, and... well, if it's Minagho again, no one wants a repeat of Staunton, right?

I have a Communal one.

Alright, come on over here and hand it out, she'll tell you who. 

A couple moments later Hulrun also starts making his way to where Anevia and Irabeth are waiting.

Meander meander.

"Alright. We're not going for an ambush here, there still might be an innocent explanation for this, but I want everyone prepared for the possibility that this is Minagho in the flesh..."

She goes through their plan.

"...and if it's Minagho, we hope to all the gods those trinkets you've been blessing really are lucky."

"Nevi! We're public officials, we can't go promoting that kind of superstition!"
