'Quelvila-Toht

 'Quelvila-Toht is the Epolian homeworld.

Quelvila-Toht is characterized by the extreme variation in its weather: the poles and the equator of the planet are hostile to most lifeforms, and vast and terrible storms sweep across the habitable areas. As such, the Epolians have evolved to move quickly across many types of terrain.

Excessive mining and deforestation have, in recent centuries, resulted in even more extreme weather, rendering the Epolian homeworld almost uninhabitable. Several million Epolians still live there, but most have left to travel the stars.

The planet was once only known as Quelvila-Toht; the apostrophe, unintelligible to organics but transmitted wirelessly between networked cybernetics, was added after the merging of organic and synthetic life as a gesture of peace and cultural unity.
