It was the sudden rapid movement of the Cocos plate and the accompanying earthquakes and volcanism, not the limited nuclear exchanges that took place around that time, that made the Earth uninhabitable and forced humankind to abandon its birth planet. Nevertheless, all human emigrants carried with them the story that human actions had caused the destruction of the world.

MOUNTAINS

The gornaya (GOR-na-ya) is the great central massif lifted by the surging of the Cocos plate, with perpetually snow-covered peaks that are higher than any oxygen-breather can climb. Because most peaks are constantly invisible in clouds, they are not used as landmarks and are almost never named. Instead, rivers and lakes are used as landmarks, with their deep valleys forming both the highways and the habitats. The border of the gornaya was determined, before the return of the humans, by the lowest elevation where the digger/angel symbiosis could survive.

SEAS

Because the folding of the land into the ranges of the gornaya left most ranges running southeast to northwest, the rivers also run in those directions. This, rather than sunrise, the north star, or magnetic north, determined the cardinal directions of the diggers and angels (they had no compasses and even on clear days could rarely see the north star and could see sunrise or sunset only at the edges of the gornaya). Thus "north" in the names of various places means northwest of the gornaya, "west" means southwest, "south" means southeast, and "east" means northeast.

North Sea-the remnant of the Gulf of Mexieo, a narrow sea jammed between the Texas/Veracruz coast on one side and the Yucatan coast on the other.

East Sea (Gulf of Florida)-a new sea opened in the straits between Cuba and Florida by the new rotation and northeastward movement of the Appalachian plate.

South Sea-the remnant of the Caribbean Sea

West Sea-the Pacific Ocean

WILDERNESS

On the Atlantic side, the gornaya gives way to a great fan of lowlands, much of it raised up from the ocean floor, covered with rich soil eroded from the gornaya and carried by great rivers which deposit new soil during flood seasons every year. The jungles there are rich with life, but since vast areas spend part of the year under muddy water, most of the fauna is arboreal. Diggers and angels who lived near the edges of the gornaya often sent hunting expeditions out into the wilderness, but they never went farther than the distance they could travel to carry game home before it spoiled. Three great regions of jungle are distinguished by the angels and diggers; their names were translated into the language of the Nafari and Elemaki and eventually those names replaced the names in the digger and angel languages.

Severless (SEV-er-less)-The great north wilderness, including the land that used to be Chiapas and Yucatan. The great rivers Tsidorek and Jatvarek flow through it; the Milirek marks its western and Dry Bay its eastern boundary.

Vostoiless (voe-STOY-less)-the great east wilderness, including the land that used to be Cuba, which forms most of the northern shore and a mountainous peninsula running eastward. The Vostoireg and Svereg Rivers flow through the lowland plain. The Mebbereg, the third great river of the east, is generally regarded as the southern boundary of the Vostoiless.

Yugless (YOOG-less)-the great south wilderness, which includes a low, wide isthmus between the Pacific and the Caribbean and reaches eastward to include a mountainous peninsula made up of what were once Jamaica and Haiti (or Hispaniola). The Zidomeg flows out of the land of Nafai down into the heart of the Yugless, and the northern boundary is the land of Nafai and the land of Pristan, where the humans first landed.

Opustoshan (oh-POOSS-toe-shahn)-in contrast to the well-watered jungles of the three great wildernesses, the fourth uninhabited land was called "desolation" by the diggers and angels because, being in the rain shadow of the gornaya, the area just west of the Milirek is desperately dry, to the point the vast regions are nothing but blowing sand. Soon the land rises to the old Mexican plateau, however, but the diggers and angels regarded it all as uninhabitable.

LAKES

An anomaly in the gornaya consists of a region of subsidence running on a north-south line, where rivers, whether flowing "north" or "south," formed lakes. As the rivers wore deeper channels into the mountains, the lakes subsided incrementally, forming fertile terraces up the canyon walls, so that the shores of the lakes have fertile land ranging from a few meters to as much as five kilometers in width. The seven lakes are named, from "east" to "west" (as the angels and diggers thought of them; we would say from north to south):

Severed-fed and drained by the Svereg

Uprod-source of the Ureg

Prod-source of the Padurek

Mebbekod-fed and drained by the Mebbereg

Sidonod-source of the Tsidorek, which flows through Darakemba and, farther downstream, the eastern reaches of Bodika. Issipod-source of one branch of the Issibek Poropod-fed and drained by the Proporeg

RIVERS

There are thousands of rivers in the gornaya, running in every canyon and valley. Though the entire gornaya is within the tropics, shifting winds and the extremely high mountain ranges cleft by long, deep valleys cause adjoining watersheds to have completely different amounts of precipitation at different seasons-of the year. Rivers are highways, landmarks, and, where the gornaya opfcns ap into wide valleys, they are the source of life in all seasons. Seven great rivers flow out of the gornaya and, after passing through wilderness, to the Atlantic. Four great rivers flow into the Pacific. In addition, some of the rivers have major tributaries. In the religion of the angels, rivers have varying degrees of holiness; the rivers are presented here according to their order in their hierarchy of sacredness (though the names are now a mish-mash of human, angel, and digger names and forms).

The Seven Lake Rivers

Tsidorek-the holiest river, flows north from the lake Sidonod. Because the lake comes near the top of the river valley, there is no major river flowing into it. Therefore Sidonod is the "pure source" of the Tsidorek, and it also has a tributary, the Padurek, which flows from a pure source (Prod), making the water twice pure. Darakemba, the capital of Motiak's kingdom, is located near where the canyon first widens into a broad valley where intensive agriculture is possible.

Issibek-flows north from lake Issipod, a pure source. It has a major south-flowing tributary, only the two rivers don't so much join as collide head-on. They once formed a lake there, which filled the long canyon for fifty kilometers before it spilled over the lowest pass in the oceanside range. But the lake eventually found an outlet through a system of caves and drained completely. Now the rivers seem to collide head-on, and since they flood at opposite times of the year, there is always enough water that the outlet is underwater. The result is that the river seems to flow downhill from the lake until it comes to a tumultuous low point, whereupon the valley goes up and the river continues, flowing in the opposite direction. The outlet runs underground for kilometers until it erupts from a cave on the other side of the range and flows into the Pacific. The outlet once had another name, but before the coming of the humans, a digger proved that it was the outlet of the Issibek. However, the river that flows north from lake Issipod and its tributary that flows south to join it are still considered to be the same river, but with two sources, one pure and one not. It is this strange river that Ilihiak's expedition to find Darakemba followed by mistake, leading them past Darakemba (several giant mountain ranges over) and eventually down into the desert of Opustoshen, where, on the shores of a seasonal river (bone dry at the time), they found bodies and weaponry suggesting that a devastating battle had been fought there. The corpses were so perfectly preserved in the desert that they could have been five or five hundred years old. Nearby, they found written records in an unknown language.
