Joy and sadness themselves are the playthings of Inurkxoi, one of the Four Powers of Entropy, as it manipulates the neurotransmitters and emotions of others as it pleases. This leads to boundless, unhinged hedonism, but also its opposite in the form of the ascetic darkness and despair of deep depression. Anything that leads to a strong emotion is favored, regardless of its cause and regardless of its outcome. In this way, Inurkxoi is both ally and enemy to its siblings as it seeks to cultivate strong positive or negative feelings purely for their own sakes.

Inurkxoi’s followers often war against those of the other Powers or are warred upon in turn. The former includes the Dopamine Reavers, whose pleasure centers light up with acts of depravity and destruction, while the later includes the Order of Deprivation, which runs a series of ascetic monasteries designed to strip sensation out of living beings.
