Helium-3 is a light non-radioactive isotope of Helium. It is used as fuel for nuclear fusion power plants. It is very limited on planets like Earth, however there are large amounts located on places like Earth's moon and other select areas. In the Leijiverse, it is used for powering of the most high-tech and sophisticated vessels such as spaceships and Metanoids.
