The Dimensional Fusion Bomb is an extremely powerful explosive developed on planet Arturus. 5 seconds after activation, it explodes sending everything within a radius of 3 parsecs (1017 ft.) is sent to another dimension. Before detonating it radiates a pulse of white light.
The criminal Stolvan Sprug obtained one of these and threatened use if the city does not pay him 50,000 ions. It was stolen from him by another criminal Braxton Red. After Red was fatally wounded by lawman Brick Bardo he activated it hoping to take out Brick with him. Thankfully Brick reached a safe distance before it detonated.
