Report what you've discovered to Thisalee Crow at Sethria's Roost in Mount Hyjal.
<This elaborate book contains hundreds of vellum pages bound within a slate cover. It's written in many languages, most unfamiliar. Carefully inked illustrations depict sorcerers or even entire buildings vanishing into curtains of shadow.>
<Many illustrations depict magical artifices like those you see around camp. You suspect the dragon Sethria is trying to keep something hidden. Thisalee will want to hear about this!>
