I've made a terrible mistake...

So I get this quest to go to the Eastern Plaguelands.Fair enough, but don't really know how to get there.So... I start swimming.Seriously. Swimming in the middle of nowhere.I eventually come to some kind of hidden piece of land that I find interesting enough to explore.Seen here: http://ift.tt/2q3g8Tf seems like its out in the middle of nowhere with no real purpose to it, right?Well, there's a dwarven house built into the ground.Seen here: http://ift.tt/2rnUY6c walk inside.This is what I find: http://ift.tt/2q3ib9I the couple I intruded on...I am deeply sorry.
