Amendments to a Certain Story

I've decided that, as I continue to modify and flesh out the world in which Fangheart lives, and the society of which he is a product, the summarization of its components should be changed as well.
Stand by for the first amendment to Changelings: A Summary, featuring the written language of changelings, and the songs of history. I'll probably follow it up with the arts, and education, and then the use of a duodecimal counting system, and... forgive me, and also humor my enthusiasm.
