Nathaniel was within the training grounds, between the barracks of the Sword and Seeker, having decided to do something to take out his frustrations, he had set up some target dummies to vent.
His two colts were completely emptied, the thing's heads and part of their torsos now virtually non-existant, he held up the guns, slides now locked backwards, with the spent casings pooled around his feet. He slammed the pistols back into their holsters as they were, and reached for his cross slayer.
Hefting the weapon up to rest with its shorter end facing towards the last, untouched, target, he pivoted the handle and pulled the trigger. There was the sudden sound of rushing gas, before within a split second this gas was ignited, resulting in a fwump sound as the brass rod left the tube mounted just above the flamethrower's nozzle, and the rod shot towards the target.
As it impacted the casing, which was cracking right now, was thrown outwards, shredding parts of the dummy, before barely milliseconds later the igniting fuel began to virtually vaporize the target.
Dropping the cross on it's "foot", he slid open the panel and began adjusting the inner workings of the fuel rod gun.
