Okay, the paper from the guard of Armadyl now: "Alas, I regret to inform you of a dire situation, which I know you worked hard to prevent. My name is Idria. I am a leader, of sorts, of the Guardians of Armadyl. I realise that you made a supreme effort in preventing Lucien from gaining the staff of Armadyl. Please accept my gratitude for your efforts in this endeavour, however, it seems that the resourceful Lucien has found another route to our beloved treasure. We believe a certain treasure hunter by the name of Movario had something to do with this, but, ofcourse, there is no proof. For my own part, I wish you well and advise you be on your guard against Lucien's machinations. Yours most respectfully, Idria." Got an idea. It says that Lucien found a new route. Maybe the new route is the sealed door? Just a wild guess.
