When falls the Iron Rain, be brave. be brave
Iron Rain refers to the invasion of a planet, satellite or asteroid by delivering troops from orbit. Legions of Golds and Obsidians would be dropped from starship while equipped with their StarShell armors. StarShells are loaded into spitTubes, where they are first held in place by metal teeth and then moved into the spitTube's magnetic stream for launch.
During The Conquering, Seneca au Grimmus was the first Gold to touch land in the Iron Rain that took the American eastern seaboard on Earth.
