I’ve seen that stone head near the embassy, but I’ve never gotten sent there by a quest. I’m still wondering.
That little welcome from Potema is so creepy. She’s going to be ticked when she realizes that Ulfis is not there to become her undead BFF. Dawnbreaker is really neat, but what a mess! It’s a looter’s nightmare!

Styrr might want to look into turning off that flame trap once the catacombs are safe, or they all might be named Firebeard.

A summoned wolf in the lair of the Wolf Queen, nice!
I love that alchemy station right before the refuge. Something for the draugr to do in their off time, or just a little warning: seriously, you’re going to need more potions!
