Xorothian Stardust

So you come to me seeking Xorothian stardust? You wish to open a portal to Xoroth, the domain of Hel'nurath my rival? Perhaps you plan to steal from him one of his precious dreadsteeds? Very well. My servant Ur'dan has a supply of Xorothian stardust. You may obtain it from him... if you can pay the price.
