V.e. Schwab said this quote

Myths do not happen all at once. They do not spring forth whole into the world. They form slowly, rolled between the hands of time until their edges smooth, until the saying of the story gives enough weight to the words—to the memories—to keep them rolling on their own. But all stories start somewhere, and that night, as Rhy Maresh walked through the streets of London, a new myth was taking shape.
