The warriors of the Horde have much to teach you, adventurer, but you must also seek out new techniques on your own. As you may know, there is a group of hostile quilboars to the east. Another fledgling warrior ventured into their territory some time ago, and never returned. He was experimenting with engraving mystical runes onto his equipment to improve his combat prowess. Find the rune among the quilboar and learn this technique yourself. Return to me when you have done so.
