The Nemesis World

The Nemesis World is the sixth planet of the Ta System.

The planet has a highly eccentric, elliptical orbit, and passes in close proximity to the World of Ta every 9999 years, wreaking havoc on the World of Ta causing fires, hurricane force winds, earthquakes, tsunamis and other cataclysmic events as the planet passes by.

It's existence and effects are described in the Nemesis Codex as written by Astrid of Kymirra in the Third Cycle.
