Biome

Each planet usually has a commonly formed terrain that has the same type of decorator or color; these are called biomes, and they’re made to make it easier for players to differentiate their locations. Please do note that:
 * Not all playthroughs guarantee you that all of these biomes be present
 * Names given to these biomes are just a placeholder, hence it's unofficial
 * Detailed information regarding biomes can be found within the planet's pages
 * If you found a biome that isn't listed here, please create a new discussion next to the edit tab, including at least one screenshot of the said biome.
