After leaving Redwater Den, we meet a man called Stalleo in the wilds. He implores us to help him, some rival of his has captured Treva's Watch and holds his family hostage inside. He wants me to liberate the fort, so he and his men can organise a search party for his loved ones. I can enter the fort via a hidden entrance, taking these bandits by surprise. Lydia seems particularly bloodthirsty today, for she sprints of into the tunnels, effectively hunting these lowlifes down.
After rooting around a bit in the cellars, we make a gruesome discovery. A couple of dead civilians, probably Stalleo's family.

We rust out quick to tell him this unfortunate news, but once confronted with him I cannot bring myself to tell him.

Shamefaced, we head back to the road. We stop for the night in Ivarstead, and early morning we make our way back to Falkreath. The Jarl there is generous with his rewards and grants us the opportunity to become Thane of Falkreath. First, though, we must make ourselves popular with the locals. As expected, the villagers do not hestitate to come to us with their requests. The one the blacksmith gave us will be something to tell the grandchildren. He wants us to find a good hunting dog, sighted along the roads close to Falkreath. Finding the beast was no trouble, however, finding that it could
talk was something else entirely!

Turns out he is a servant of Clavicus Vile, another Daedric lord. Learning this, I quickly look to rid myself of this creature. It wants me to meet it at Haemar's Cave. Sadly, I already cleared this vampire den of it's inhabitants. Otherwise the fates might have bestowed me the luck of having this dog devoured by the bloodsuckers. It can sit at the cave until world's end, for all I care.
The rest of the tasks for the people of Falkreath were done quickly enough. I now can call myself Thane of Whiterun and Thane of Falkreath. Another follower has joined our party as well. Rayya, my new housecarl, will surely make herself usefull.
