[Quest] Forgotten Name

Keep in mind that I don't have all the details worked out yet. The premise of the quest is that you stumble across the name of either a weapon or set of armor. Preferably, you would find this in a book. Anyways, the quest has you talking to various people about the armor/weapon, however the name of the armor/weapon has one of those spells that makes people forget what they were saying. For example, The Rock of Kuthian from Inheritance. So basically you go around looking for clues towards the location of the armor/weapon and the reward for the quest is the actual armor/weapon. I imagined this quest after playing the quest "A Night To Remember" from Skyrim. If you haven't played it, check it out it's really cool.
