The user is able to create, shape and manipulate ice ages; a period of long-term reduction in the temperature of the planet's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers. Ice ages can be devastating on a planet’s climate and ecosystem. An ice age isn't simply an elongated winter, but a dramatic decrease in global temperature. It doesn't lock a planet into a season, but instead will make all seasons colder.
