Klaus & Werner (K&W) specializes in the production of personal and spacecraft-based energy weaponry. Established in SEY 2893 by a former designer from Behring, the founder sought to pursue his vision independently after feeling undervalued in his previous role. K&W's product range includes various repeaters such as the Bulldog, Badger, Panther, Rhino, Galdereen, and Mammoth, along with personal firearms like the Demeco Energy LMG, Arrowhead Sniper Rifle, Gallant Energy Rifle, and the Arclight II pistol, which gained significant attention on the spectrum show The Frontier.
