"That's gonna make this an interestin' ordeal," Reno noted. "We're gonna have to ship you a load of potatoes every time we wanna ship a load of potatoes. Buyin' 'em from here'll just put the farmers on Gaia outta business."

"I wonder if there's some kinda way to use materia in the place of your chakra stuff. Put a slot in the scroll, slip a materia in, let the scrolls run on the planet's energy, instead. It ain't anything as big a deal as what people were doin' before, and if it means people might be able to eat or get medicine, they might even go for it."

Really, he was pulling it out of his ass as he went, but if materia could heal a person or let someone light things on fire on a whim, they could probably put things inside a piece of paper... right?
