Tranquility Valley National Park is a large valley located on the planet Mars, located due-east of the city of Ninjing, the valley gained its namesake, because it was the landing site of the first Ark Ship, named 'Tranquility' which landed near the valley on the 21st November 2072 after its five-month journey from Earth. The ship now stands in the valley, and serves as a museum to the colonisation of the planet Mars, aswell as Land-That-Was.
