Zem

This Slavic acid fantasy snowflake is the world of Zem. The Hill Cantons is a region proper (a loose collection of poorly-run borderlands cantons ostensibly ruled by the Overking), the name of the ten-year campaign--and of course now a four-part published series to be ignored and smiled at indulgently like an eccentric uncle.

Zem is a world divided into four near-symmetrical parts, double bisected by the World Canal, domed by the heavenly firmament, and riding on the shell of the World Turtle that swims in a spiraling loop through the cosmic void. It is believed to have its reflection in an mirroring Anti-Reality.
