|Location||Coldridge Valley, Dun Morogh|
A Letter to Grelin Whitebeard is forwarded to him from Talin Keeneye for the second part of the quest chain Coldridge Valley Mail Delivery. Grelin was sent here by the The Senate of Ironforge to "investigate the threat posed by the trolls" in Coldridge Valley, and this letter - signed by the King's own hand - orders Mr. Whitebeard to find an expedient solution to the problems.
Now Grelin and his brother Senir Whitebeard were sent out to deal with the trolls alone, because the Senate has its hands full dealing with just the troggs. The King seemed pretty vocal in his last dispatch and Grelin is no man to let his King down, so he finds a solution in local recruits.
One night, such a foray stumbled upon Whitebeard's unattended camp and stole Grelin Whitebeard's Journal. The only thing he saw of the thief was that "it was a big brute with markings on his skin and face". This particular Troll turned out to be Grik'nir the Cold. After reobtaining his journal, Grelin finishes his report and - trusting the heroes more than his bumbling apprentice - sends them off to his brother in Kharanos with Grelin's Report.
He starts the following quests:
-  in which Grelin requires you to eliminate 8 Frostmane Troll Whelps.
-  in which Grelin has you go to the troll cave and slay Grik'nir the Cold in order to reobtain Grelin Whitebeard's Journal.
-  in which you are sent to talk with Mountaineer Thalos before hazarding the Coldridge Pass.
