The Reach surrounds the perimeters of the inhabited Atria and refers to the buffer zone between the colonized world and the depths of Infra that have yet to be plumbed by proper-type folks. It is dotted with small fortresses with shack and lean-to towns sprung up around them, inhabited by all kinds of people. The Reach represents a harsher life-style, less cultivated and managed than that of the people who inhabit the Atria.
The Reach boasts everything a man, elf, or gnoll could hope to see in the Atria and, in some cases, more. It bears some beasts that have never been cataloged and maps depicting different borders and different formations of rock appear yearly from explorers who swear up and down that it looks one way or the other.
Those who inhabit the Reach are hardy folk, by the standards of any of the nations of Infra, and are viewed as perhaps a bit reckless or world-weary. To come from the Reach is to be willing to face the perils of the Farther as well as the tiresomeness of those people who live in the Atria. Skirmishes betwixt the nations still occur in the Reach as resources are found and vied for by companies and bodies of merchants who have no official ties to their respective governing bodies.
Inhabitants of this buffer area also speak of things that live deeper in the bowels of the Earth, the regions referred to as the Farther — places farther out than most have dared to travel.
