Eyeroll. "I mean, I don't, but I'd sort of expect that if 'all unsent end up terrorizing people' then there is some condition of becoming unsent that requires you'd terrorize people, and would either exclude Kaede or they– they? – would have to become the type of person to terrorize people to do it."

"—why would anyone terrorise anyone, here."

"I'm not clear on what you mean."

"Likewise."

"I suspect that if unsent terrorize people like fiends do then in order to become an unsent you will somehow terrorize people in some way, whether it alters your personality or how it manifests or you have to in fact be the type of person who would terrorize someone as a prerequisite to becoming an unsent, and because of this, though I do not know whether it is accurate because I don't know if the data is 'literally all unsent terrorize people', I am not sure if you would be able to become an unsent in the typical way without going and terrorizing people and I assume you have some fix thought of, plan on one, or alternatively it's a non-issue of some sort."

"Unsent do not terrorise people like fiends do."

"What do they do, then? Literally stay as immortal disembodied souls?"

"Yes."

"So. How do you go about becoming unsent upon death and why is it not preferred to the– potentially-illusory whatever? Is it just a religious thing? I don't have details on that thing, the Farplace or whatever, either."

"Well most people can't stay as unsent, if it were easy no one'd become a fiend. You need to have something you strongly care about here, something to hold you in Spira."

"– Not clear on these things. Fiends are when people die and do decide to terrorize people, or what?"

"I already explained this. Fiends are when people cannot move on on their own, and their grief twists them into monsters."

"And unsent are when people feel strongly that they need to stay as disembodied spirits, and– everyone else is just people who decide they don't need to stay for various reasons?"

"This was already explained, too. Very few people decide to stay. It is a summoner's duty to send them on their way to the Farplane so they won't hang around as fiends."

"I object to sending unsent, though, for obvious reasons."

"Is sending unsent to the Farplane, uh, an easy thing to do? Could you instead help tether them here so they don't need such strong feelings to stay or something?" Pause. "I honestly don't know if this will help in any way, I'm just wondering if this is in fact a thing you could do, and if so how much preparation it'd require if any."

"If it could be done, I'd be doing it. Well, maybe, if it was very complicated then defeating Sin might still be the highest-leverage option. But no, as far as I know no external force invented yet can keep a dead person here. Or—bring them back."

"And why do you think the things in the Farplane are illusions? I'm not clear on why they can't just be weird manifestations of the spirits or something – are people both there and out as fiends or unsent, is that an easy thing to check…?"

"I don't think they're illusions, or not just illusions at any rate—people don't appear in the Farplane unless they're dead and sent. But elsewhere you can totally get pyreflies to show you illusions of loved ones regardless of how dead they are and the ones you see on the Farplane are pretty similar."

"Oh," he says. "I think I might have an unclear idea of this thing, then, since I'm forgetting bits and apparently misremembering things. What parts of your Plan might actually change now I'm here, and what do you have in your plan for after you die and hopefully become unsent – just work with people from there and hope you have extra information after doing the summoning?"

"Maybe now you'll pay attention," she says in a not-very-low voice.

"Worst-case scenario I just kill Sin again and again, however many times I need to, but I'm planning on gathering as much information as I can about it on the way there and there. The way you change stuff is that you may actually be a way to kill Sin and keep it dead, somehow."

Theo gives Lulu a bit of a look, then says, "So you can still do magic while you're an unsent, or whatever you need to be able to do summonings? And I don't know, it might be of help, but it seems to have pretty drastic limitations when it comes to fiends and this seems like a step up."

"I can still do magic while I'm an unsent, I don't know if I can still summon while I'm an unsent but I'm betting I can, and in any case the Final Summoning is a terrible palliative and I want to find something better."

"Right," says Theo. "I don't suppose you know where any unsent summoners happen to be, since I guess you probably would have checked in with them?"
