"Their names were Jiang Yanli and Jin Zixuan. They died--well, in the mess that happened after the war."

Nod. "Were they involved before that? I'm mostly concerned about unintentionally starting the war again."

"That's unlikely as long as you don't resurrect anyone surnamed Wen, although raising Wei Wuxian would have its own set of problems. The Wen sect was the most powerful of the five great cultivation sects, but they became arrogant and attacked the rest, who were forced to band together to destroy them. Wei Wuxian took in refugee civilians from the Wen Clan, but he was using dangerous and untested magic and things went very badly."

"That sounds straightforward enough, all right."

"Wei Wuxian's body was destroyed utterly."

Raafi nods. "That doesn't matter, for True Resurrection - I actually don't even need very much for the resurrection spell that I can do now, a lock of hair taken from the body is fine, or ashes from a pyre, if you do that here. And the political situation might have calmed down in five or ten years, especially with the casualties returned to life; we'll have to wait and see."

...Nod. 

"No ashes. No hair. There was nothing. But five or ten years is acceptable." Is infinitely better than forever, which is what he thought was on offer. 

"Mmhmm. If your undead problem is widespread, it's good news, that way - I expect it makes it dangerous to travel, and if I can clear it up, that should be impressive enough to get my god's attention. Maybe not enough for an entire tier, that takes a lot at this point, but a good piece of one."

"It would be extremely rare and unfortunate for a ghoul problem to make travel difficult for long without one of the sects addressing it."

"Well, good news in some sense, if not in this one. I may be able to solve it permanently, though, which will still count for something. And there are plenty of other things I can do - even just exploring by myself helps, it's just slower."

"...Solve it permanently?"

"I can consecrate an area so that no undead can rise there. Doing it permanently on a large area will take time and be expensive, but it's probably worth the effort even if you have it basically under control - the difference between a low risk of meeting a walking corpse and no risk is significant, to most travelers, in my experience."

"What are the relevant magnitudes of 'large area,' 'take time,' and 'expensive.'"

"It takes several spells, and supplies - if I'm focused just on that I should be able to consecrate an acre in a week or so, with enough powdered silver; I'd have to check my notes on how much, but a considerable amount."

"One acre is unlikely to make a considerable difference. Unless you could do it to something like the Burial Mounds..."

"It does make sense to start where most of the corpses are."

"It's not just the number of corpses, the place is very cursed."

"Well, that sounds like another problem I can solve."

"Normally it's the kind of problem we can solve but nobody's been able to make any headway there."

"It's still worth a try. Usually it comes down to caster tier, in my world, higher tier spellcasters can put more force behind their spells. And fifteenth tier casters are rare enough that I won't be very surprised if you don't have anyone equivalent around, even if I'm not approaching the problem from a different enough perspective to matter."

"Fifteenth tier?"

"Mmhmm. Just like how spells come in distinct tiers, spellcasters do too, in my world, based on how experienced they are. It affects how well my spells work, in various ways - higher tier casters can produce more food with the conjuration I showed you, and resurrect people who've been dead longer, and for other spells they'll last longer or have a larger or stronger effect or can be cast at more of a distance, things like that. You'll notice that the number fifteen, or multiples of it, comes up often in what my spells can do; that's usually because of my caster tier, and they'll improve when I do. Higher tier casters also get more spells, and higher tier ones; I'll be able to cast ninth tier spells when I reach the seventeenth caster tier, out of twenty possible."

"If I hadn't had a concrete demonstration of your power that would sound like nonsense." 

"It is a little strange," he nods. "We think it has to do with how magic was made by the gods, that it's easier for them to work with us if spellcasters can be categorized more simply."

"As far as we know, the gods had nothing to do with our magic."
