A Noble Expedition

Background
A Noble Expedition begins immediatly after your conversation with Trian Aeducan and Bhelen Aeducan. You are send to an ruined thaig to recover the Aeducan Family Shield.

Walkthrough
You'll start of on a road with Gorim as companion. Take the only open way leading into the stones. On your way to the first scout, Frandlin Ivo you'll encounter your first beast, a Giant Spider and shortly after the first two Genlocks. After you met Frandlin, take the south east road since the others are dead ends (the only one containing enemys will eventually open later on). After fighting another group of Genlocks, you'll meet the second Scout who will also become a temporary companion. Leading on, you'll have to fight another group of Darkspawn (Genlocks again). Once you reach the door to the chamber which is supposed to be sealed, a conversation will start. When entering the chamber, you'll meet some mercenaries. The leader will happily tell you how he managed to enter, no matter what options you choose you gotta fight them in the end. Make sure to stay out of range of the Ballista firing at you. After the fight you might loot the bodys and chests, however taking anything but poultrices is poinless. The room containing the shield is marked on the map. Gorim will start a dialog again, but it doesn't really matter what you order your companions to do. In the middle of the room there is a sarcophagus, left, right and in front of it are some stepstones. Position your companions on those and approach the sarcophagus. You may open it with your ring and recover the shield. When leaving the room you are attacked by some darkspawn again, this time accompanied by a Blight Wolf. If you don't want to run all the way back you came, take the ballista bolts from the container next to the first ballista and load the rear one with those. This will open a short path back to the room where you met Frandlin. On your way you'll have to fight some Deep Stalker. After the fight you'll meet your beloved brother who appearently tried to kill you to get the shield for himself. Depending on how you reacted to Bhelens accusations after the feast, you'll either have to kill him or he'll be dead already. Once it's over your Father and the others will approach, asking what you've done. No matter* what you say, in the end you'll be imprisoned.

* This needs to be reviewed since I didn't try all options.

Result
You're imprisoned, The Exile starts.
