Hey!
Where can i get the quest to go to Shrine of Mehrunes dagon?
I thinking of getting daendra hearts, when i get there the door is locked.

Be warned that he is not a nice Mehrunes.


Search around Dawnstar for a museum.

Once you are high enough level, a messenger will approach you telling you that he has a message from a friend. When he gives it to you, you see that it's an add asking you to visit a museum in Dawnstar. Go there, and the quest will kick off.

I am pretty sure that you need to be level 20 before the messenger brings you the letter that starts the Mehrunes Dagon quest.
