Mergis

Mergis was a small, dense planet in the Lefei System with a highly-corrosive atmosphere. The planet was difficult to inhabit, however it had one notable population centre, Mergis City, where most of Mergis' population lived. Mergis was mostly inhabited by Humans. The mythological city of Erbisterra was said to exist on Mergis.

Geography & Climate
Mergis was a small planet, with little features of note. It's surface was rocky and sandy, however it was an abundant source of rare metals. Mergis was much denser than similarly-sized planets.

Economy
Mergis had a strong economy, despite the poverty which many of its citizens lived in. The rare metals abundant in its crust made mining operations incredibly profitable and because of its proximity to Oysakkooferous, which was an exporter of many more common metals, the Lefei Dockyards were one of the cheapest and most convenient places to manufacture ships in Galaxia.
