The Extrinsic known as Hunger was the first creation of Order and Chaos, born of their deep-rooted need to reassemble what had been lost in the same fracturing of the Whole that had created them. Its terrible deviation from that purpose resulted in its becoming the bringer of entropy, annihilation, and endings.

Hunger had been intended to take the bubbles of Froth - the shards of creation - that were the mortal universes, and to refine them into forms more suitable for reconstruction, but in the end its own insatiable hunger drove it to consume all universes it encountered, and at last to turn on its creators, in an attempt to recreate the Whole within itself. The nature of the struggle that ensued is now unclear, for neither of the Diarchs wish to speak of it, but it ended with Hunger being bound and imprisoned.

In its shackled state, Hunger is no longer in a position to consume other Extrinsics; but out of all of them, only Order and Chaos can match it in power, and then only with utmost effort. They have warned all their other children to keep away from it, to neither speak with it nor interact with it, and never to seek to free it, and this has, by and large, been scrupulously observed.

Though it can no longer directly consume universes, Hunger's continued existence exerts a less direct but more insidious influence on them; it is Hunger that is responsible for entropy, for the slow breaking down of matter and energy into a homogeneous void with which nothing more can be done and from which nothing more will come forth. Hunger is, in short, the root of not merely individual deaths, but the deaths of universes. It is these universes, spent and wasted, that Order and Chaos feed it so that they can be drawn forth again to produce new vitality.

Its sole form of interaction with mortals, aside from assisting in rendering them down to their most basic components, is with those individuals that share enough of its contempt for existence that they might become its willing agents.

Hunger craves the unity of all things within itself with a terrible desperation. The very existence of separate beings, of heterogeneity, of activity and movement, enrages and affronts it to a state of madness. It is largely incoherent, neither willing nor able to speak except in the most basic and primal of terms; its ability to think has largely decayed in favor of its all-consuming hunger, and its ingenuity, limited in any case, is largely devoted to quickening the pace of annihilation.

Hunger's realm consists only of emptiness, its void occupied only by its black, silent howl. Unlike the realms of other Extrinsics, where mortals may well have at least a chance of survival (however slim and conditional), to enter the Realm of Hunger is to immediately cease to exist, and indeed to have ever existed at all; the victim will be retroactively erased.

The only mortals to have any kind of direct encounter with Hunger are the Doomtouched, who only rarely speak of it; but what little has been gleaned from them, in addition to whatever tales told by Chaos in her sojourns into the mortal world, has often morphed into myths of gods of doom or destruction, of chthonic beasts and sea-monsters, or of accounts of the foretold end of the world.
