Investigating the Merchants' League Estate

This quest is gained by talking to Aldeth Sashenstar in front of the Merchants' League Estate. In order for him to be there you must have sided with him at his hut in the first Cloakwood otherwise his brother Dabron Sashenstar will be there and will attack you. When you talk to him he'll say that something is off at the Merchants' League and that his two partners Irlentree and Zorl have been acting weird and making bad buisness decisions. You'll be asked to investigate this and invited inside the Estate. Once inside go to the 2nd floor and in the southern room, inside a locked desk there are documents from which you will learn the truth, that Irlentree and Zorl are actually doppledangers. From here you can choose one of two paths: No matter the path you chose, after you have killed all the doppledangers, talk to Aldeth to get your reward.
 * Talk to and give the documents to Brandilar - a guard on the secon floor. He wants you to kill the doppledangers right away and immidietly after the conversation the merchants will start to turn into doppledangers which you have to kill.
 * Give the documents to Aldeth and he will lead you the 3rd floor to his fake anniversary party where you will confirm what was in the letters and learn that the doppledangers were sent by their master Rieltar. After the dialogue all the merchants in the room will turn into doppledangers and turn hostile.
