Aethertech are selling handcrafted steampunk style brass and wood rayguns.
Utilized to manage undead threats through aetheric emission: the Omicron Wavelength!
In real life Gywnn Tavares, the shop owner, points out that the raygun’s switch controls a flickering amber glow on the gun.
Back in the steampunk cosplay world, Aethertech explain how the zombie hunting guns work.
As men and women of Science, you are no doubt aware that animate dead and vampires have the ability to sense life, even through walls! Aethertech Industries discovered in 1871 that they are in fact able to detect the radiation given off by the aetheric body associated with human life forms and conveyed in the low frequency luminferous aetheric spectrum. The Omicron Wavelength is an aetheric emission that interferes with this prey sense. Hence, it may be employed to convince these unliving creatures that the source of the Omicron wavelength is something that tastes truly repellant: it literally projects bad taste.
