fleshing out the design for the plumbers working in the pods. http://kiabugboy.deviantart.com/art/The-pods-566496103

plumbers are one of the worst jobs one could have in the pods, their daily task is to patrol the tight, dim corridors of the plumbing sector under each level of the cities in the pods. they have to repair broken pipes or replace old ones, and monitor gas pressure for leaks. worse yet it is common place for breaches to happen in the pods and most of the time, it happens in the plumbing sector, so incidents often happen where areas would be sealed due to creatures invading the area and usually many plumbers would be stuck to defend for themselves. so lots of plumbers would carry a few make-shift weapons from whatever they can gather and weld together.
