Crushing Blue is a story I came up with rather late in the creation of The Heels of the Unknown. It was not part of the original 8 stories finalized on August 15, 2015. Indeed, I didn't come up with it until January 12, 2016, a day after I came up with Starfall, when I decided to replace a story about The Benefactor. So anyways, that's all I can think to say up here, so onto the endnotes!
