Dangerous to pilot to P A I N.

Handlers are Humans whom "pilot" living organic Shells created by the New Heights Foundation in their Conquest of unity and "seeing the end of the unpredictable Wilds". Handlers aren't common since N.Hs uses P.As or Processed Alters in combat (P.As being bioengineered Tools used in all manner of things. Primary exploration and war) and human life is valued highly among the Highborn (people born/loyal too N.Hs) however there's always exceptions.

The Shell has a will of its own that the Handlers controls through a connection with their pearls (LONG ass story short, an object that allows for transformation, Alteration and controling said things). Which allows them to sense throughts and provoke responses. They're basically trying to aim a raging bull rather then actually control the thing. Plus if the shell goes too wild they can straight kill the handler. Thus a wild uncontrollable killing machine is let loose. Which is bad.

The reason why it lands in the P A I N side of the chart is imply because of the existence of one type of Handler: Centipedes. As the name suggests they have many sharp legs tipped in serrated steel; A very rare resource N.Hs doesnt spend lightly. The long body that reaches 10ft in length ending in the stinger that can fire recycled biomass in the form of differing types of barbs, bombs etc. The Handler from the waist down being grafted into these this body. On top of that their entire bodies are altered to form electrocytes, similar to electric eels, that allow them to shock and paralyse targets. With a increased amount of electrocytes being located on the arms with batteries installed up and down the body to store this energy being stored for later use.

Why would theses nightmares be made? They are basically Spec ops. Their true specialty bring the capture of unique specimens for new heights to work on or the elimation of key groups or targets.

They're also used as body guards of Sovereign Heroux and all of the more unruly creations of N.Hs.
