“There were some things that needed to be said even if the person you were saying them to didn't understand; words that must be released from their trapped place where their flapping to get out could cause internal damage.”

“All we could get out of them was that they were taking us to 'Kurokuma'. We didn't know if that was a place or a person. What does it mean, by the way?''I'm told it's a term of great respect,' Horace said, unwilling to admit that he didn't know.”

And the words people said were just shadow of real things. But some things were too big to be really trapped in words, and even the words were too powerful to be completely tamed by writing.”
