Lucy turns a fingertip diamond and starts scratching Correspondence on the glass.

When she’s finished, she reaches into her mouth and pulls out a brightly-glowing diamond tooth, then put it in the lantern.

”For healing people without using spell slots once I’ve left. Be very careful with it if the glass breaks; unguided, my light can be… indiscriminate… in its dispensation of vitality. Exposure to it is approximately never going to be lethal but it can be very uncomfortable not to be dead.”

"- Thank you, I understand." She'll take it with care and reverence. "Will other enchantments interfere with it, such as making it harder to destroy?"

“Shouldn’t do. But I don’t think I understand local magic well enough yet to swear that it won’t be harder to enchant than normal glass—my kind of magic item doesn’t do slots.”

"Thank you." A smile.

“It’s really very little trouble compared to the expected value.”

"Then is it easy for you to make more?" A magic lantern of resurrection in every continent!

"It takes me about five minutes to carve the sigils, and less than that to re-grow the tooth. --I don't have spell slots, I can do that all day if I want to." 

"If you ever have an hour or two free." At some point they'll get towards the ten minute moment. (There's still more healing, as always - Absalom is a big city and Remove Disease and Regeneration spells, and people have picked up it does age, too, which someone somewhere might have invented at some point, in the ages before Earthfall, but not since.)

"Give me as many glass lanterns as you have, I have a vest of pockets I can put 'em in, I can do them when I have a couple minutes spare here and there." 

She'll do that!

Lucy will put all but one of the lanterns in her pockets and start carving the one she leaves out. 

"I should lend you some spells before you leave," she says thoughtfully. "Do you know the spells Sanctuary and Shield Other? I can give you them with a general Comprehend Languages."

"I don't actually know any spells as such, my abilities work differently." 

"Ah! No, how they function; I can lend you some of mine."

"Ah. No, I'm still not familiar with those two yet."

"Sanctuary stops others from attacking you as long as you don't offer them any harm, though it can be resisted; Shield Other lets you take half the harm someone else would take, and is a minor ward against spells and blows for them." Both are very useful for Sarenrites.

"--Okay, those both sound amazing, but, also--how does Sanctuary define harm, like, if I'm attempting to resurrect some vampires and the vampires object to this, does that count--"

"Broadly, though speech and curing others never count. Trying to use positive energy to destroy vampires does, certainly," she says, "I don't know about also resurrecting them."

"Oh, my light isn't positive energy, it works differently, it doesn't destroy vampires before resurrecting them." 

"Then I do not know, for no one has ever tried it before. Shield Other will last fourteen hours, Sanctuary eighty-eight seconds, and Comprehend Languages one hour, twenty-six minutes "- and then she'll do something magic and there will just be a - section of Lucy's mind that she didn't notice, with three new levers she can pull in it.

(It's very clear which is which; Shield Other is bigger and more complex, and it and Sanctuary, the two guardian-spells, are clearly similar structures. Comprehend Languages, through process of elimination, is the small one that isn't defensive.)

Oh gosh. 

Lucy's first instinct is to apply her laboratory-honed poking-at-the-neat-magic-things impulses, but fortunately, she has Wisdom enhanced instead of Cunning, so she does not immediately rush off to try to figure out some kind of magically-enhanced mirror arrangement that will let her look at the dormant spell structures now attached to her instead of Bey Xerashir. 

She does, however, promise herself that, in the mythical future in which she has downtime that isn't otherwise spoken for, she's going to have a nice long scrutinize of some spells. 

"Thank you. --Is this more like a buff, or like having spells prepared--in the sense of whether it sticks when you die and come back--"

"You are welcome." Smile. "The spell granting you the spells will end if you die or it is dispelled."

Hug before Lucy runs off to do anything else dangerous and heroic?

The Sending will come back!

"Miss Whitman, safe in Ardis, main church, all alive, elder dragon resurrected, departed, some chaos, buffs empty, get new ring, Heaven will assist, see soon."

"...The elder dragon's probably my fault," she says, grimacing. "What do you think he means by Heaven will assist, specifically--"

"Either that Heaven will help you get a new ring because you used your last one in a good cause, or that they will assist with Hell."
