During a Fighter's Guild quest, you meet a rather odd woman by the name of Drarayne Thelas, who religiously collects pillows. Odd, isn't it? Well, there was originally a quest involving her where if you found a crashed ship with her pillow invoice on it and returned it to her, she would reward you with an artifact of awesome power. Thing is, the quest is broken, and you can only complete it during the Fighters' Guild quest-Which gives no mention of it. This fixes the quest so that it works anytime you bring back the invoice- making it separate from the Fighters' Guild quest like it should be.
