The Mystery that surrounds Gwen...

Me and my friends are always puzzled about Gwen the girl just outside ascalon that follows you where ever you go if you tell her to. And at post searing you find remains of broken flutes and Gwens Broken flute. That this is allso linked in with chapter 2 somehow. Sorry if this has already been posted but can anyone shed some light on the situation please its got me and my friends confused.
