Mettilia is a planet in the Polaris System . It is highly magnetic and electrofied, and home to the Mettilians. The government consists of several warring states, vying for power through constant war. The Primers are known to ferment war among the states, and will trade weapons for electricity.

The seas of the planet are made of Ferrofluid, and are known to have huge magnetic storms that make sailing very difficult.

Mettilia is also home to large, winged Drakes, that Mettilians use as war mounts. These Drakes use the power of Mettilia's storms to fly.

Most eutrophic organisms on Mettilia use Electrosynthesis to create energy.
