HH Engineering

HH Engineering have a small warehouse and design office in Sumugan Gate, Marduk City.

They sell and re-sell small handwaved gadgets, particularly those related to the safe use of handwavium (like handwavium (manual or automatic) detectors and scanners). There's also some hard tech available, negative pressure work environments, like benches with pressure hoods, for safe working with handwavium, and some hybrid tech which also includes waldos and other remote manipulators.

None of this stuff is certified for medical work, though you could use it if you were desperate, as the waldos and manipulators are high quality and remarkably precise, and allow microscopic viewing attachments.

The staff are engineers, as well as sales staff, and are quite happy to talk about engineering problems that their products can solve. They also are willing to arrange small-scale on-site consultancy.

The actual ownership of this company is unclear, which is entirely what Brains intends, and the authorities in Marduk seem quite happy with this.
