Today there were more tremors. I told the Lieutenant it felt like something was digging deep beneath the fort, but she said I was crazy. "The ground shakes sometimes," she said with that stupid grin of hers. "And the mountains quake and the snow falls. That's life in Skyrim." Milk-drinker!
So, I did my duty and reported to my superior officer. She told me to forget about it, and so I have. I must patrol the roads around the fort now. Maybe I'll take a look at the entrance to that tomb while I'm out there. Just in case.
