It's an old ruin full of vile worshippers of the Bad Daedra. Follow the road north of here, then keep going north when the road forks off to the right. Nalmen Drinith
I sent him there, but he hasn't returned. I'm certain he has perished. You ought to tell his parents, but perhaps we can soften the blow. Go to Adursaranit and finish what poor Dralnas started. If you do find his body, see if he has his signet ring. He always carried it with him, and I'm sure it would give his parents great comfort to have it back. You can find the Daedric ruin due north of here, deeper into the woods. Nalmen Drinith
