Yetimus the Yeti Lord

For years the mountain yeti of this region have been allowed free reign. Our complacency in dealing with the yeti menace has resulted in an aberration! Yetimus, lord of all yetis, has grown to a size and strength that our guard simply cannot handle. We fear that should his appetite lead him near Tarren Mill he would devour us all. Gather a party of suitable adventurers and dispatch the beast. He roams the countryside to the west. Bring me one of his horns and I will reward you handsomely.
