"Conjure food?"

"Mmhmm. Not quite as useful as it sounds, but maybe I'll prepare that one anyway, as a demonstration. Anyway, is there anything else I should know tonight?"

"...Uh, everyone rises at five."

"All right. I might be up a bit before that, but I can be careful not to disturb anyone. Thank you for your help."

"You're welcome." 

He sleeps, and wakes up comfortably before dawn to do his devotions, pacing quietly around the room.

They'll find him sitting outside the building the next morning, reading from a notebook and nibbling on dried fruit, with a walking stick he didn't have the night before propped against the wall beside him.

"So, you're our mysterious stranger." 

"That's me!" He tucks the notebook and pouch of fruit away and stands. "I assume someone wants my story."

"That would be lovely."

"There's not much to it, exactly. I seem to be from a different world - the young man who found me last night seemed very surprised at how my magic works - and I appeared in this one in my sleep last night, I have no idea why." He's awfully cheerful about it.

"A different world?"

"Mmhmm. It's news to me, too, that there's more than one, but walking corpses are much rarer, there, and our gods are more active in the world, and our magic is different - I get my magic from Fharlanghn, our god of travel, and I can do - well, lots of things, but the ones that came up last night were positive energy channeling, which heals the living and harms undead, and food conjuration. I can demonstrate both of those, if you'd like."

"...I would very much appreciate it." 

"All right. Do you have somewhere for me to put a lot of food? It isn't stable, it'll fade after a day if it's not eaten, but at my tier I can make nearly a hundred fifty meals' worth at once."

"We do, yes." 

He leads Raafi to a storage area. 

He chants for a few seconds, and the promised food appears with a diffuse glow - bread, mostly, as loaves and smaller rolls, but also a container of oats, a bushel of apples, a large tub of butter, and a small wheel of cheese, plus a couple of barrels of water. Raafi picks up a roll and takes a bite, then grabs an apple, too.

"What are these?" he asks. Some things, like the bread, seem basically straightforward in construction, even if the details are unfamiliar. Others, like the butter and cheese, he's baffled by. 

"Butter, there, and cheese - butter is churned cream, usually spread on bread, and cheese is fermented milk. And these are apples, a kind of tree fruit, don't eat the core."

"I had guessed these were a fruit." He's still handling a cheese as though he finds it perplexing. "This is fermented, but will go bad after only a day?"

"Regular cheese doesn't; conjured food is different, the spell wears off and it stops existing correctly. Except the water, water's especially easy to conjure. It's fine to eat, though, it's just as good that way. Here-" he takes the cheese, and takes a small knife out of his belt to cut through the rind and slice off a piece for himself and a smaller one to offer back. "This is pretty plain cheese; I can get a spell that can do nicer food but it's more complicated, doesn't make a very good demonstration."

He eats the piece of cheese. "Interesting," he pronounces. 

"I can show you how to make a few of the simpler kinds, if you want. Butter, too. For now the healing demonstration, though - do you have anyone around who needs it? My basic healing spell only does the same kind of healing that you'll eventually get from rest, I'd have to prepare something specific to break a fever or restore a lost limb or anything."

"...My brother is currently recovering from an injury to his back." 

"That sounds like the right sort of thing," he nods. "Unless he's paralyzed; I can fix that, too, but it's a separate spell, it'll have to wait until tomorrow."

"He isn't paralyzed, it's all skin and muscle damage, his spine was unaffected."
