Lucia stabs it a lot, and also harvests some feathers for Aadhya. 

"I'm going to see if I can tell anything about where they all came from." 

"We didn't get any tokens," El notes, watching the rest of the students in the gym creeping back to the various activities they were distracted from. "I'll go with you but first you should dump a bunch of mana in the sharer so Aadhya and Liu can cheat and earn enough for all of us." She holds out a hand.

Lucia dumps a whole lot of mana on her, incremented in chunks sized for El to be able to handle. 

And when the sharer's filled up and Liu and Aadhya have been notified of their role in the matter they can go follow the trail of architectural damage and slime and mal ichor.

Lucia has some tracking spells; they aren't as solidly in her wheelhouse as spells to kill things are, but they're useful for what she does. And she has mundane tracking skills, developed in the streets of New York and developed over three years in this tin can. 

The results... 

"...They just came from everywhere," she says, frustrated, after the umpteenth not-quite-a-dead-end. "It's like someone set up a honeypot right in front of that door, or like the school decided that that corner of the gym specifically was out past curfew!" 

"- okay, its timekeeping isn't completely busted, Field Day is on schedule, but its clock could still be partially bollocksed up. Could there have been a honeypot? Maybe one that would be edible to the mals, so they would have eaten the evidence on the way in? I have not the foggiest about motive, mind, but..."

"May...be? Set up by whom, for what purpose--nobody with half a brain would try to assassinate us like that--"

"Not the foggiest about motive. It would have made slightly more sense before graduation when there were seniors agitating to throw a few younger kids to the hordes to appease them."

"...I wonder if there was, like, anyone we just happened to be sort of near, who could have been the target of an assassination." 

"It'd be a bloody stupid time to assassinate anyone. Everyone shows up on Field Day, it'd make more sense to honeypot their room or a class."

"I'm not saying it makes sense but explanations that make sense are a bit thin on the ground."

"Maybe someone... dropped a honeypot? By accident?"

"I don't...think they go off when you drop them? Maybe someone dropped something that wasn't intended as a honeypot but ended up having a similar effect?"

"Seems like the best notion we've got so far."

"And, of course, all evidence was destroyed." Sigh. "I'm going to find Shannon and bribe her to help fix people up some more with some of the mana I at least scrounged up from that little stunt." 

"I guess I will... go... climb ropes. Anything you fancy out of the automat if you're not back by the time we're collecting brunch?"

"I'm not picky, get me whatever anyone else wants the least." 

"See if I don't." Off she goes to climb ropes.

Lucia locates Shannon and does some bribery. 

...Nobody is going to die of their wounds, who hasn't already. Not directly. Lucia is still pretty worried about them in terms of being obvious low-hanging fruit, but--there isn't really anything she can do about that that she wasn't doing already. And it...probably helps their individual chances that it happened to a bunch of people at once? Instead of any one of them by themself?

This is not super reassuring but, like, when is anything ever. 

Lucia tries to put it out of her mind. Worrying isn't going to improve the situation, and she has her own allies now, who deserve better than for her to be pointlessly distracted. 

She rejoins them after less than fifteen minutes, there being little for her to do after Shannon has been paid unless she wants to stand over her making sure she doesn't renege, which would be pretty stupid of her. 

Liu, Aadhya, and El between them have scored a respectable brunch of egg-in-a-hole and baked beans and cran-apple juice. El has gone out of her way to specifically get Lucia a haggis with neeps.

Well, that'll successfully distract Lucia, at least for a moment. 

"So...I'm not complaining...but, uh, what is this?" she asks, poking at it with mild suspicion. 

"Sheep organs and oatmeal and onions and suet," chirps El. "And the side dish is turnips. Some poor sod ought to be very grateful you have left them something else to eat, just as you requested."

"Sheep organs, huh." She starts eating it. "I have never had anything quite like this before," she decides after several bites. "There's something to not having the real version to compare it to." 

"If I had never had haggis before perhaps this would have motivated me to keep it to myself, but alas."

"--Oh, haggis, this is haggis? I have heard of haggis. As being...Scottish? I think?"
