Some misc notes that I'll add into a post on the lore thread including the map:
Forseti is a planet with a nearly straight axis, meaning it has very mild temperatures and only reaches extremes far to the north or south, or due to land features. It is compatible to a shattered eggshell for it's continental tectonic plates, meaning it has a patchwork of volcanic islands neighboring mountain-divided continents. The ocean plates are a bit more stable, but have plenty of underwater volcanoes.
This means that, while it outwardly looks peaceful, Earthquakes are an issue on occasion. The mines are made out of sturdy Zero Alloys to compensate, and luckily while the quakes are frequent they are usually minor, the bigger quakes being less common due to the planet often relieving stress before a dangerous buildup.
