After traveling with Barbas for quite some time, he was causing my burglaries to go awry. Hence, I told him we needed a short time apart. He agreed and departed. However, I now have need of him again. I had hoped he would make it to my house, but he has not shown up. Where should I expect to find him again?

He's in that vampire-filled Haemar's cavern by the shrine of Clavicus Vile.

I suppose that makes some sense as that is where his master is. I will journey there and attempt to retrieve him. Thanks for the heads up.

This.Also it's much better than follow him .___.
