This scroll is from that scheming dryad Rynthariel, Keymaster of the Talon Den on Stonetalon Peak.
She'll not be making any more contact with the messenger you looted this from, heh, but we must stand our ground here. The Horde will not tolerate her outrunners here.
[your name], travel to the Talon Den. Kill Rynthariel, and then put up a symbol for all to see. Take this Horde flag, [your name]. Put it up in the Talon Den so that they will not be so rash as to send another messenger through our territory again.
