I gave you the Dwemer key, didn't I? The one i made from the instructions I found on the puzzle box you brought me?

What? Oh. Yes, I'd forgotten. Here's a Dwemer key, made according to the instructions I found on the puzzle box you brought me. I've no idea what it's good for. But if you take it back to Arkngthand, maybe you'll find the lock it opens.

Yes. The inscriptions on the box seem to be the directions for setting a Dwemer key to open a specific lock. If you're interested, after you've delivered your report to Caius, come back, and maybe I'll have a key you can take back to Arkngthand.

The little cube I'm looking for is about the size of a fist, maybe a little bigger. It will be made of a coppery metal, with a circular design and symbols on one side and some lined marks on the other sides. That's all I want, that little cube.
