Remus is the third planet in the system, which is called the Romulan Lack of lack of a more precise designation. It has an extremely slow rotation around its own axis, so it is always facing the sun on the same side. Together with the neighboring planet, Romulus, they are often called sister planets. Most likely, these are binary planets that revolve around a common center of gravity of the system, similar to the Earth and the Moon. So there is constant light in one hemisphere and darkness in the other. There are rich deposits of prized dilithium on the planet. It is inhabited by a type of Réman who, after the arrival of the Romulans, became essentially their slaves.
