Speak with Doran Steelwing about the headdress and the gravestone.
<You take a closer look at the gravestone. It is of Doran's son Dulin. You decide to return to him and speak with him about it.>
Aye?
I am sorry fer not speakin' the whole truth. Ye see, today would've been my son Dulin's sixteenth birthday, the age at which Wildhammers become men of the skies. <Doran's voice is trembling and you can hear his throat closing up> He sadly died... My lass Sigrun never recovered from this day forward, her heart was too broken... She developed a sickness, one that took a heavy toll on her health. We tried everythin' we could, but, alas... On her deathbed, I promised her to make Dulin his headdress, but I couldn't bring myself to do it... <Doran takes a moment and procures a gryphon carving from his bag> Thank ye so very much, friend. Ye helped this ole dwarf find closure...Take this, Dulin made it fer me, when he was a wee lad... Please, if yer ever feel like needing a home, Aerie Peak will always have an open sky fer ye.
