Hmm, it's hard to explain you how. You must go to the folder gameserver/data/jscript/quests and find there the noblesse quest(I don't remember what is it's normal name). Then you delete all the folders and you copy/paste the end of the quest to the start. That means that you will copy/paste the last folder and make it first but don't delete the beginning of the quest. Then you must edit the html so that it will need only one npc for the quest. Then you just change the npc names and ID's.
