Forscan VI is the third planet from the system's sun, and one of the system's most naturally beautiful planets. Instead of a surface ocean, Forscan VI is bisected by a large saltwater lake. The land to the west of the lake consists of coastal wetlands that give way to a fertile prairie valley. High mountain ranges to the north and south keep the moisture from escaping to the polar regions and keep winter storms from encroaching into the valley. The eastern half of the planet is starkly different. It is marked by volcanos and churning magma fields that have given rise to craggy mountains and winding cave systems. Toxic gasses prevent widespread development, except for mining settlements which seek to take advantage of the rare ores brought to the surface by volcanic activity.
Field Marshal Shawn Veldn specifically selected Forscan VI to serve as the base of operations for the "River Rats", Tresario's amphibious operations unit. The planet is ideal due to the various climates it provides for the Rats to be trained in year-round. Rivers, swamps, mountains, deserts, glaciers, grasslands, and caves; all provide the Rats with a variety of terrain to practice the guerrilla tactics they would be applying toward their enemies. Field Marshall Velden organizes scenarios for the Rats to endure psychological tests, fitness and swim tests, obstacle courses, land navigation drills, and long ruck marches under harsh conditions.
