Death of the Endless is neither blessed nor merciful, nor is she a creepy old man with a scythe. Certainly not- she is a pale and heartbreakingly lovely girl-next-door who's just doing her job. (Also, she has a floppy hat collection, and loves happy endings and Mary Poppins.)
You'll feel, deep in your bones, that you know her from somewhere. Like she was your oldest, dearest friend. You would love to meet her- and sooner or later, we all do. You'll hear the sound of her wings...
