After you have collected all of the Dragon Priest Masks, head back to Labyrinthian, but don't go inside. Head to the centre of the massive courtyard, and locate a large raised circle. Go inside and you will find a wooden mask. Equip this mask and you will be transported back in time to the same place. Here you will find the Dragon Priest Shrine. Put all 8 of the Dragon Masks on here and the Konahrik Mask will appear. You may now take all of the other masks back as well as Konahrik.
