Reward: 1500 Renown, 16000 Gold.
After taking the Quest Card teleport back to Hook Coast. The city is under Screamer attack. Once again go to the magically sealed passage, fighting them off. Guild Master will read the incantations and it will open. You will encounter Maze in there, who apparently betrayed the Guild and joined Jack's side. Theresa will free you from his magical chains and you'll have to fight the him. Don't attack him when he has Physical Shield on, it will wear off in a few seconds. Focus on dodging his attacks, and hit him as hard as you can once the shield is down. The evil sorcerer will teleport himself a few times to different parts of the area. When he's in the lighthouse, you'll have to smash the door with your sword. When you eventually defeat the fallen Hero, he'll start to have second thoughts about his betrayal, but will die nonetheless. It's time to find out if you really are capable of stopping Jack of Blades.
