Robert walked into the armory and looked around. He saw quite a bunch of people working on weapons and tools. It was as expected, after all they were in a war. Being a child of Hephaestus, he was supposed to make his own weapon. He was impatient to get started. The sooner he finished with his own weapon, the sooner he could help other campers get their weapons. He went to an open workstation and started working immediately, somehow knowing how to use all of the tools, knowing where everything was and what to do. He remembered his magical pack that could summon anything he needed. Robert worked patiently at the forge.
Robert finally finished creating his awesome new weapon. It was a celestial bronze MP5. Modified to be used by ambidextrous users (being one himself) It fire celestial bronze rounds, as well as had a celestial bronze stock to bludgeon monsters with. He also gave it some added modifications for whatever was needed. Smiling, he stepped back and watched, wiping sweat from his brow. He needed to get the thing tested before anything, so grabbed and hurried to test it out.
