Tamsa II is a gas giant in the Tamsa system, United Empire of Earth (UEE). Unlike the former rogue planet Tamsa I, it naturally formed in the wide accretion disk that orbits the black hole at the center of the system. The internal heat of Tamsa II is very low, with an upper atmospheric temperature of around 200 degrees Celsius. However, the deepest sections of its mantle are just hot enough to decompose methane into elemental carbon. Once formed, the carbon then floats upwards and combines with other carbon atoms to become diamonds. These diamonds rain down into the mantle, where they are broken into carbon again, and the cycle repeats.
