A theory I didn't really hear discussed was that Dusk was always a part of Manus. Perhaps after the Furitve Pygmy died (the first time), was when pieces of his soul had split off. One of them may have become Dusk of Oolacile. If so, this would explain why Manus kidnapped Dusk and why he felt "A wrenching nostalgia, a lost joy, an object of obsession, and a sincere hope to reclaim it." Additionally, it would explain why Dusk was not driven to madness like Artorias or any of the other citizens of Oolacile. The event that day may have pushed Dusk to discovering the truth. We know that in the present, Dusk was captured by a Crystal Golem, and that the Broken Pendant was found in the Duke's Archives. Perhaps to discover more about Manus and her possible connection to him, she went to the Duke's Archives for answers. She may have found them, causing her to become what she is now.

But all speculation, of course.
