So I went back to Volkihar Castle to see if the Bonehawk jewelry respawns (it does) and helped myself to some books and what-not. Recently got the Fence perk and so no worries.

Couple (RL) hours later leaving my home and get attacked by a group of thugs. On one's body is a note from Modhna saying to punish me for being a thief. So of course I've seen this for other characters but can't place who she is.

She was a vampire at Castle Volkihar and I wiped them out over a month (in-game) ago. Ha!

Now I have to go and find her body because I'm OCD like that.

I still have their bodies rotting in the castle.

Did you find the Werewolf Pelt? That was pretty cool.

It's not like she hasn't been dead before... Maybe she's foxing?
