Tralphium, also known as helium-3, is one of the main power sources of early advanced space flight. The first time this resource was mined on a large scale was by the kurlians in the 2260s BCE. Tralphium is located all over the Milky Way and humans started using it for their interplanetary-drives and AE-Drives until the UGR introduced them to the Hydrogen-Helium Battery in the 2290s.
