Go to the top of the stone steps at Mason's Folly and meet Wrathion there to accept your reward.
<Wrathion's piercing red eyes fixate on you.>
You are among a rare breed, <name>.
You are just what I am looking for - an individual with the potential to shape events on a global scale.
Come now, I promised you a reward, and you shall have it! East of this tavern is a series of stone steps leading up to a vista that the locals have named "Mason's Folly." Meet me there.
