I have been looking all over for these [censored] wererwolves. I found Castle Karstaag Ruins(Which was full of reiklings). I found Castle Karstaag Caverns, but it seems like the actual Castle Karstaag is just not on my map. Where is it?

You already found it. Just the ruins (and Kaarstag's remains ) are there.

Castle Karstaag Ruins is the castle. There is a giant chair there. Go to the Glacial Cave and find the skull. Bring it back to the ruins, place it on the chair and then run like hell.

unless your feeling like a bad azz at that time

I underestimated Karstaag the first time. I threw a sweet roll at him, making fun of him for the lack of such a tasty treat in Solstheim. He then one hit killed me.

Okay, minus the sweet roll part that is all true. But Karstaag is scary. I had to have a follower, a pet, and a summoned dragonborn come and help me defeat him while I ran around and dodged swings.

I used fireballs, atronach's, Lydia, and Dragon's Aspect. The 3rd time I managed to kill him, while Lydia was hollaring at him saying, "I came a long way just to kill you." Loved every minute of it. It was worth dying to hear her say that. lol

Uhm.....then where are the werewolves? I was told a group of werewolves were hiding out in Karstaag, but there are none, and the map marker is not the same map marker as indicated via an image search?

There are none. There is however a group of werewolves hiding out at Frostmoon Crag.

Where is that?
