Magic will still be there in the morning, and they might even have someone more qualified to teach it, so.

That's entirely reasonable, and they only have to endure a bit of pouting from Temperance.

Reon doesn't sleep, instead he just spends the night making notes and thinking.

And the next morning, there's someone else with Naruto, waiting in the common area. He's dressed far more simply than the blond, with a clean white shirt and black pants and a straight sword at his waist. 

His eyes turn to them when they emerge, but he doesn't say anything.

"Hey guys! Morning! This's Uchiha Sasuke - Sasuke, these're Temperance, Phelix, and Reon."

"Hi!" Temperance says brightly. He is looking entirely human today.

"Morning, it's a honor to meet you."

That's guy sure is sure himself. Phelix will smile brightly. "Hello. I hope we didn't disrupt your schedule too much with our sudden appereance."

"You didn't." A pause. "It's good to meet you. You're from - another dimension?"

"Correct, we were trying to find a world to travel too and the magic got out of control, landing us here."

"There's weaknesses around our dimension. We're easier to fall towards. Why were you trying to find a world?"

"Entities that have often been referred to as deities decided to cover it in darkness and monsters, after several centuries of steadily worse fertility problems, all for the sake of powering a ritual that allowed them to commit suicide."

"Weakness? What weakness?"

To Temperance: "Worlds have natural barriers that make travel between them harder for our magic. Ours were pierced."

To Reon: "And I suppose you want to seek asylum, then?"

"Huh, that's has fascinating implications. Was it done on purpose? Or maybe it's a natural phenomenon?"

Phelix's answers in Reon's behalf. "Yes. At least we need is a place where our population can mend and recover. We are hoping that, given time, we should be able to find more worlds or even fix ours."

"We don't know where the barrier came from. The piercing was the result of someone's technique."

And to Phelix: "We do have empty lands, and a need for people to work."

"What sort of resources do you have to transport and settle people?"

"In massive numbers? We're working on building trains, which could carry large numbers. Our roads are in good shape, and cars have been easy to import and implement. Both cars and trains are mechanical ways of moving things and people. For settling - it depends on the region. My nation is one of the more fertile, and has settled refugees before, but is small. Fire is large, and their current administration is competent, and they might be able to repurpose their internal refugee systems."

"Interdimensionally, I can open portals, though only a few at a time."

"A few total? Are they permanent?"

"Fascinating. We have ways to improve crop fertility and growth rate, though we don't have the actual land to do that. Would you say that given the current state, they would prefer permanent settlers or temporary ones?"

"I have to actively hold them open. My nation would prefer permanent settlers, and I suspect the same of Fire - our problem is a population crash, a few temporary workers to stop the crops from rotting would help but not solve the underlying problem, though people who plan to stay twenty years then leave would fill the same need."

"We are made aware of the population problem, yes. I am sure most would rather move once and stay than move twice in a short period."

"We want to find other uninhabited worlds for the sake of resources and also as a potential bribery to get surviving rulers to cooperate nicely and get their vassals to do the same. Of course, things are sufficiently wrecked that the benefit of doing that might be minimal."

"Then we'll start setting out a call. There's some precautions we'll want to take - mostly around disease."
