Because they are beings of cacophonic energy, it is impossible to maintain prolonged control of a disharmonian. As such, they are not often kept as slaves for longer than a few hours. As such, they are usually created with a purpose in mind, a specific target, and once they have dispatched that target, they are abandoned by their creators. Sometimes the disharmonians go back and kill their creators if they can, but usually, they have forgotten their creator and the torments that formed them. Those that do retain memories rarely have enough mental wellness to survive very long.

Because they dislike sunlight, they usually find caves to hide in. Eventually, they make their way deep underground (if they did not start there) where stones and crystals are abundant. Their voices are ill-suited for communication with mortals, but they are able to understand each other. Thus, they often end up joining one another in small bands. These small groups are very fluid--they often change membership as disharmonians wander off on their own, find other bands, or otherwise leave. They generally have no distinguishable leaders; instead, they compete for resources in a rough but not fatal fashion and take care to teach newcomers how to survive.

Bands of disharmonians maintain small territories which they expand as the individuals in the band grow stronger. Eventually, they create large caverns due to their diets, and they begin to become concerned with structural integrity of their territory. At this point, they begin targeting living victims whose bones provide them with much more sustenance in smaller doses and do not threaten to collapse their caverns in on them. Generally, this is when some disharmonians take on hunter roles, while others become builders and tunnelers.

Some rare bands grow into cities of disharmonians. These are rudimentary in their social structure--they are far too disconnected and individual to form lasting communities--but are very, very powerful and dangerous. These cities are usually bright and colorful metal and stone structures that look more like hives of tunnels and pockets within the underground.

Having no memory of their past selves, they retain nothing of their former cultures. They do sometimes form their own new disharmonians, though this is rare and only done if there is a need for more in their band or city (for instance, if they need more people to dig tunnels). Though they do procreate themselves occasionally, they have no strong bonds with their children beyond teaching them enough to get by. They have no genders, no romance, no love. Only survival.

The fluidity of their bands/cities means that there is always a shifting population. This means a constant exchange of information and also a weak retention of information. They are known for their care in what they share and don't share, only giving what they need to get by or get ahead.

Though they are inmortal, the instability of the caverns they live in leads to a high mortality rate none-the-less.
