The Abandoned part is true. Until we get an Act 3 or Act 4 or whatever placing it in there, it technically isn't confirmed, just assumed (I've made this same argument with Chrono Story). If this is another series, mothy isn't giving it a name, as he's even named End of the Four, Original Sin Story, Seven Deadly Sins, and Clockwork Lullaby on his blog. I know songs like Wendy and Little Match Girl have been speculated as Freesis Fairytales. You never know.
