The action begins in Refuge of Edhelion, a city near Thorin's Gate. Talk to Talagan Silvertongue. Search Haerandir's body and equip the items you've found. Talk to Talagan once more. Go down the stairs and follow Edehlben. When you are left alone, you'll have to defeat 5 invaders. Go forth all the time, fighting each of them separately. Speak with Dorongur when he opens a gate for you. Elrond will appear and save you and your companions. After a scene talk to him, and you'll be done with the first part of the tutorial.
