The Scroll of Valdire

Start
To start this quest, you must talk to the Highwayman at the crossroads between Draynor and Varrock. He tells you that he would rob from you, only he has some other "prey" to tend to. Press the matter, and he will attack you. However, he is only level 15 and has a very weak attack. Dropping his health below 20% will cause a cutscene to in sue. The thief will tell the player dejectedly about how he was going to steal a great scroll from a great adventurer. If you tells him he will live, he doesn't believe you and will feint.

The Adventurer
After the highwayman has been "killed", you can find the Adventurer along the North past. He will be reading a map, and looking quite confused. Talk to him, and inquire where he's going. He will tell you his name, Arnold, and his story.

The Box of Valdire
A thousand years ago, a mage explorer was hiring for a partner to storm the Temple of Valdire. Our dear Arnold jumped at the chance, and they invaded together. The Temple was guarded by armed, magical monks, and Arnold was invaluable in breaking through the ranks. The team of adventurers slew some monks, and incapacitated others, before they found the treasure room of Valdire. This mage found the Box of Valdire, and turned on Arnold: he stole his soul and used it's power to teleport the treasure and him away. When Arnold awoke, he was in the dungeon of the temple, as a prisoner of the monks. However, without his soul, he found he could not die. After nearly a thousand years of horrible cruelty at the hands of the monks, he escaped.

The Wizards' Tower
Hell bent on revenge, Arnold wanted to steal the box back and retrieve his soul. However, to do this, he would need the Scroll of Valdire. This is where luck smiled on Arnold - the Scroll of Valdire will always tell the reader the current of the Box of Valdire, and will give the holder control of the box. Arnold traveled to the Wizards' Tower to find The mage, who had been using the box's power to keep himself alive. In the tower, he found the Scroll of Valdire in the Phylactery Room. On the way out, he had to work strenuously to avoid the sight of the the mage, who had been using the box's power to keep himself alive.
