"Do you prefer your shocking revelations spaced out or all at once?"

"Let's go with all at once." 

"The three of us are from two separate, alternate Earths, my brother and I from the early twenty-first century in a world where a small percentage of girls have magical powers, and she's from an earlier Earth where there's all kinds of weird magic things such as stars being people."

"Earths? Twenty-first century--goodness. Well. If this isn't all some kind of prank in very poor taste, that's--fascinating."

"Professor, you were dead. It's not a prank."

"Well, I have only your word, and this gravestone, which would be difficult but not impossible to set up just for a prank, as to that, don't I." 

"Do you not remember -" She looks at Lucy. "Is there some known reason he wouldn't remember?"

"Sssssometimes, like, if you died of a blow to the head or in your sleep or something, you won't happen to have been conscious before you're alive again...? But, like, that's in the Neath where people come back on their own, it wouldn't have been days in those cases..."

"How can someone be conscious without being alive?" 

"...The soulless are really a minority back home, I'm not sure I ever interrogated any of them if they remembered being dead, maybe you need a soul to do it." 

"Well, anyway, you can look at the time and notice you're missing some," says Isabella. "Also we can, like, demonstrate additional magic." She materializes a little wand with a star on the end and waves it around.

He climbs out of the coffin, noticing for the first time that his hands are no longer wrinkled and lined and liver-spotted. He holds them up and admires them. "Well, this is better than I had any right to expect. Why, er, me? My focus isn't the most recent..."

"No, but your death is." 

"Well, there is that." 

"I was looking through obituaries. I figured you'd think we were interesting, even if our Earths aren't the one the 'Verse was settled from, and you'd do for a native guide, and we were able to find your body. We've been sort of bumbling around; we got on the Cortex but there's only so much that can do in a total context void."

"Oh. Well, ah...I would invite you to stay with me, but, er, I suspect if I attempt to show up at my house like this my son will have no idea who I am, so."

"Yeah, sorry. I'd apologize for not finding a young accident victim but that would have resulted in, uh, postponing your resurrection till we figure out how Lucy can scale up, so that would be an odd apology. We have a hotel, I can afford another bed. - our current financial situation is that I can magically generate pearls and other organic material of value and sell it."

"How does that work?"

"I have shapeshifting powers. The wings are real. I can't look completely baseline human, and if I get too weird I go crazy, but within the band of humanlikeness I can occupy, I can do whatever I want, including grow pearls. Things I grow still exist when removed from my person - as distinct from my clothes or this," she waves the magic wand and drops it illustratively. It vanishes. "Which I can control but not pawn."

"Fascinating. If you had asked me yesterday--er--the last time I was, ah, alive, that is, what magic would look like--well, not that I expected magic to be real at all, but if I had I don't think I would have expected that." 

"My magic is completely different!" 

"Oh?" 

"Remember the bit she said about stars being people?" 

"--I hadn't quite caught the significance at the time, but now that you mention it--" 

"I am one-quarter star and this gives me all kinds of goodies." 

"One-quarter--how does that work?" 

"I have made a specific point of not asking."

"And I am Isabella's totally normal human twin brother. - her name's Isabella. I'm Xander."

"And I'm Lucy!" 

"Pleased to meet you all--you already know my name, of course. Well. Thank you. Very much. I do very much prefer not being dead." 

"I hoped that would be the case! Can you help us get introduced to the 'Verse? Our interests include resurrecting more people."

"Well, I--er--certainly, although, unless you just want to do more of the same," he gestures at the torn-open coffin and earth, "perhaps it would be best to find somewhere not here to be, I'll have to think about it, I'm sure I know more about what's going on than you do but how to resurrect people given magic systems I've never read in a fantasy novel is certainly not something I've given much in the way of thought to before." 

"Casually ripping open lots of graves has issues, like - you mentioned your son wouldn't know who you were, imagine hundreds of displaced people with no homes to go back to. Someone would notice, but who? What would their opinion on the situation be and what would they do about it? We don't know. Also, like, if we managed something sufficiently streamlined, I bet she can go a lot faster if someone else does the digging and puts bodies on a conveyor belt."

"Yes, that sounds extremely reasonable. Er, young lady, are these the clothes I was buried in, and does whatever you did to bring me back clean them, because if yes and no respectively I would very much like a bath and clean clothes." 

"Most of my resurrectees aren't as impatient about that part. I need to put your coffin back." 

"Yes, yes, alright." 

"Please be patient, we're working on less context than we'd like and I'm trying very hard to learn to be responsible with my terrifying amounts of power because back home everything was needlessly complicated and even if I set almost everything on fire achieving my goals it was still an unambiguous improvement." 

"...Ah." 

"Wait. Damn. Isabella, did that come out like a threat."

"Little bit. Professor, I have never seen her literally set anything on fire."
