In order to acquire Konahrik, you must locate all 8 dragon priest masks (9 including the wooden mask, which is required to access the central room) and place them on their busts in Bromjunaar Sanctuary, which is located in the sprawling ruin of Labyrinthian, which is located here[www.google.com]. The place you're looking for is a dome shaped structure roughly in the center of the ruin. Upon entering, you will a find a wooden mask near a dead body. Should you don the mask, you'll notice you were transported to a restored Bromjunaar Sanctuary, with the busts intact. To leave, simply unequip the mask, and to return, wear it again. Remember to keep this it, as you need it to access the mask chamber in order to acquire Konahrik.

As a general warning to any low-level or otherwise ill-prepared adventurers, getting the masks is not a particularly easy task. The dragon priests themselves are very deadly adversaries, and many are located at the end of dungeons filled with difficult enemies. Not to mention Labyrinthian is infested with frost trolls.
