This quest is called 'Yak! Yak! Yak!',
for Adventurers levels 120 to 179.
Lord Agrippa [Runic Castle] is the master in charge of this quest.
I recently got to the bottom of my 'In' box, and it turns out that
several years ago Gnyah Yakslayer turned in a request for permission to rid
the world of all rabid yaks. Since his request was never answered,
apparently he has been just rotting away in the castle waiting patiently for
some word regarding his request. Please go to him now, and inform him that
his request has been approved. Unfortunately after all this time, Gnyah is
too old and frail to do his duty so I am assigning you to use your young,
spry body to complete his quest, and rid the world of all yaks. Your
service will be greatly rewarded upon your return with a report of your
activities. May the Powers guide and protect you!
Upon successful completion of this quest you can receive:
*Up to 59 quest points, 6 practice points, 38,000 experience points,
 0 build points, 0 piety, and 9,000 gold pieces.
You have 220 minutes remaining to complete this quest.
