"We might want to leave it there while we repair the wall but maybe I could get a few bits out laprascopically?"

"I think what I want to do is leave it in until we're ready to fix the wall, and then when we take the wall down we can see what we can salvage from where we can reach it. I feel fine, just--conspicuous." 

"We can swing by my room, pick up a few more crystals before too many people see you."

"Awesome. Hey, El, does the Junior Prophesied Dark Sorceress Kit happen to contain any dark, concealing cloaks?"

"...huh, let me think. Uh - no, I think that'll make you radioactive - hm - not sure I can avoid accidentally making a nightshroud if - okay, got it, top me off?"

"--Well, I was joking, but sure!" 

Uhhh how much is too much--right the night they met--she passes over an approximately mortal flame sized amount.

El whispers in ominous Kauravi and Lucia is engulfed in a pillar of blackness. It gives Lucia a kind of HUD, like a low-saturation video game except for all the apertures and people in her field of view popping up in red. "You don't want to do that in direct sunlight but we're not so much as swinging through the caf," El remarks lightly.

"What a fascinating life you lead."

"Amazing. What happens in direct sunlight?" 

"Oh, the spell absorbs light and turns it into a low grade sterilization field, I got it when I wanted to disinfect a cut but the original fellow wanted to both look ominous and kill anyone who got in his personal space while withering all the grass where he walked. It's related to the one that would've made you radioactive but in this light it won't even give us sunburns."

"You get the most amazing spells. Next time you need to clean a cut I have disinfectant." 

She starts moving towards the stairs. 

"Was that the time you traded me three weeks of snack tokens for rubbing alcohol?"

"Yep."

"Am I going to be extra-sanitary when we take it down?"

"Probably, yeah!"

"Cool. Ooh, I bet this spell would be good for, like, sterilizing hospital rooms, or pest control--I'm sure the mana cost is too high for practical use. But I'm going to enjoy it while it's up." 

"I'm sure there are better spells when all you want is to kill some bacteria."

"Or cockroaches. --Man, I wonder if the Void would go even harder if you asked for spells to kill stuff. Probably best not to test it." 

"I have studiously avoided taking creative writing classes after my first attempt."

"Oh, no, what happened?"

"Supervolcano."

"--Wow. Setting off an existing one, or making one out of whole cloth?"

"Oh, I'm sure it would have served for either."

"Huh...could you prevent one from going off, if it were going to?"

"Maybe direct it, not stop it."
