I have a question. When I asked the innkeeper in Dawnstar about rumours he said something like this: "we all know about the Black door but noone dares to go there" or something like that. This did not reveal anything on the map or in the quest log. Anyone come cross this?!

I play on Xbox.

I think that is referring to the entrance to the Dark Brotherhood Sanctuary in the rock face close to Dawnstar.

Aaaah.. Of course. That would make sense. Tanks for that
