After the Imperial Guard took notice of the old Rogues' Den, Brian O'Richard shut down his maze and opened the doors to his Flash Powder Factory instead. Inside players can operate the factory, while dodging obstacles and the sneaky fingers of other players. Some Thieving experience can be gained from pickpocketing other players as well as Herblore experience from mixing ingredients at the Factory. Pieces of the old Rogues' Den rewards can also be found lying around.
