Volkanite Disintegrator

The Volkanite Disintegrator is an advanced form of a man-portable, thermal ray Volkite Weapon employed by the military forces of the Leagues of Votann. A Volkanite Disintegrator is one of a class of powerful thermal ray weapons whose technology is pre-Imperial in origin and dates back to the Age of Technology. These weapons possessed considerable killing power, surpassing most other man-portable armaments of their size.

Blasts from Volkite Weapons were even known to be able to penetrate the thick ceramite plates of Space Marine power armour with one concentrated shot. Volkite Weapons produced a deflagrating attack, in which subsonic combustion caused by a beam of thermal energy propagated through a target material by thermodynamic heat transfer so that hot burning material heated the next layer of cold material and ignited it. A Volkite Weapon's heat ray had a devastating effect on organic matter, explosively burning flesh into ash and jetting fire.

However, Kin weapons like the Volkanite Disintegrator are superior in almost every respect to those patterns of Volkite Weapons wielded by the agents and military of the Imperium, since the Kin employ superlative materials and methods in their construction and have no fear of further innovating on an ancient STC design. As a result, the Volkanite Disintegrator and other Kin Volkanite weapons often have longer ranges and more stopping power than any of their Imperial equivalents.

In this case, the Volkanite Disintegrator is based on a form of the technology that has been lost to the Imperium for millennia, and the Adeptus Mechanicus would give much to get it back.
