Gerra

Gerra is a super-Earth located in the Gehum star system. It is the location of Gwiddle Earth and 'The continent' where the United Regions is located. Gerra is roughly 3x the size of Earth.

It was the capital planet of the Gwilym Republic until the 3rd year of the 13th age (2016) when they change it to Graxia due to them becoming worried that the people of the The Continent will find out that there is a huge space empire next door.

Gwilyms still populate Gerra as there are still around 20 billion Gwilyms there.
