I recently completed a quest in Eastmarch near Jorunn's Stand that ended with Hadmal Lastblood. I actually felt sad (read this).....

Then I realised how brilliant this game and the developers are in invoking that feeling in me from a game.
I now look forward to Pacrooti's and Gavin's daily mails. Gavin recently hired a strong arm to protect him from being attacked. He asked what was his name and he replied that it was immaterial. Gavin thought this was a strange name.
These are the hidden gems in this game. I'm sure that there are many more. Keep up the good work.
