I'm very sure there are still some Daedric Shrines, caverns, Dwemer Ruins, Barrows, and what not still to be discovered.
I opted to build my Estate right over the ocean where I can watch the ships come and go as well as those other explorers, tradesmen, nobles, and maybe even a few beggars walk up the slight slope from the dock and get their first view of the wonderful place called, Raven Rock.
For now, I'll abide my time making sure things run smoothly around here and that the needs of the people are met so that we may live as peacefully as possible.
That is, until they need a savior again.....
