Description
Here - if you are interested in learning more about the Feast of Winter Veil, read this book. While I think our recognition of the legend is the appropriate one, I'm enough of a scholar to appreciate the collection of all information into a single source.
When you're done, take the book to Muradin Bronzebeard. I know for a fact he'd be interested in hearing that others have taken an interest in the older legends.
