The Pole Tunnels & The Core

The Pole Tunnels

From the north and south poles of any Lattice World, there reaches into the interior of the planet a smooth tunnel, four kilometers wide and over 8,000 kilometers deep. Called the Pole Tunnels, these smooth-bore holes through the planet's shell provide the only accessway between the surface and the core.

On many Lattice Worlds, atmospheric and meteorologic effects have combined with lack of maintenance to "cap over" the tunnels at the poles. The inhabitants of such worlds commonly lose knowledge of the Core (and by extension to the other worlds of the Lattice); thereby is a Lattice World with its pole tunnels thus sealed commonly considered barbaric, and often a prime target for conquering.

Gravity at the pole ends of the tunnels is the standard seven-tenths of an Earth gravity, but decreases as one moves down the tunnel toward the Core. Within the Core, the Pole Tunnels become hollow tubes of 200-meter-thick iron foam.

Near the center of the Core, two accessways called the Fluteholes, two kilometers in diameter, open into the sides of the Pole Tunnels -- one is situated north of the In-Teeg, opening into the northern Pole Tunnel; and one south of the Out-Teeg, opening into the Southern Pole Tunnel.

The Core

At the center of every Lattice World exists a hollow space 343 kilometers in diameter. Here lie most of the true wonders of the Lattice Worlds.

Within the Core, there is weightlessness.
