Caius didn't leave much for me to go on, and I'm beginning to think its time to march on up to Red Mountain and take out Dagroth Ur. I tried that today, but I whacked on him for 15 minutes with no noticeable effect. Before I attacked him, he mentioned something about my needing tools.
I'd also like to upgrade my few pieces of Ebony and Orcish armor, I've only got 3 pieces of Daedric and would like to see more.
Any help would be appreciated, even a point-me-in-the-right-direction. Thanks.
