===Put Him Out of Our Misery!===
[[File:SR-quest-A Daedra's Best Friend 03.jpg|thumb|right|Barbas at Clavicus Vile's statue]]
Back at Haemar's Shame, the map marker will point towards the cavern entrance, which will force you to travel through the entire cave system once again. To circumvent this, head west up the road
for about 10 seconds until the path bends. A pine is growing on the left, against the mountain wall; the back entrance is behind this tree below the top of the tree. Reaching the back entrance is fairly easy. If you reach the first piled up set of rocks on the left, you've gone too far. Note that this only works if you previously opened the spike gate by pulling the chain behind Clavicus Vile's statue. Otherwise, the gate will be closed and you will not be able to access the room. Inside the cavern, Barbas will once again sit in front of his master. When approached, Clavicus Vile has one final prank to play and will give you a choice: you can keep the Rueful Axe if you use it to kill Barbas. The dog will understandably jump up and try to tell you that it is not the only option available. Speak to Barbas and Clavicus Vile for further elaboration and make a decision. Kill Barbas and keep the Rueful Axe, or hand the axe to Clavicus Vile and receive his true daedric artifact, namely the [[Skyrim:Masque of Clavicus Vile|Masque of Clavicus Vile]]. Note that both items are unique, but only the Masque of Clavicus Vile counts towards the [[Skyrim:Achievements|Oblivion Walker]] achievement, so it is recommended to keep Barbas alive. Regardless of your choice, Barbas and Clavicus Vile will be reunited and you will receive your reward. Finally, return to [[Skyrim:Lod|Lod]] in Falkreath for a small amount of gold and his gratitude.
