The Leng Device is a fiendishly complicated set of machinery, covered with a faint blue haze.
This massive automaton is made up of dozens of metal containers, there is smell of ozone in the air
In between the machinery are containers of various shapes: rows of urns and several large glass tanks filled with foul green liquid, atop the apparatus are rows of vials, crystals, the machinery is constantly moving; a whirr of spinning gears hisses of steam.
The various small vials and tanks hold strange herbs, some have brains and other body parts, coils crisscross the apparatus, various metal rods spark with blue electric flames, others with strange purple eldritch energy.
The machinery apparatus s large enough that its upper parts are accessed by a metal catwalk.
