Jasper Dimmerchasm was a shield dwarf member of the Zhentarim and prisoner of the fire giants in Ironslag sometime after the War of the Silver Marches.[1]


In the late 1480s or early 1490s DR Jasper went to negotiate with Duke Zalto. However, the lord of Ironslag decided he did not need the Zhent's help and captured him. Zalto put the shield dwarf inside the head of his iron maul weapon.[1]
