Remenium

Remenium is a rare element almost exclusively found in the Remian System which has various gravitational abilities. It comes in two types: normal Remenium (green in colour, shiny), and Charged Remenium (pink in colour, holds electrical charge). Only the normal variety came be found naturally.

In the past it was used for only creating artificial gravity in spacecraft, but as the Remies progressed, so did their uses for Remenium. It is now used for lifts, automobiles, goods transport and high speed train networks. For example, the element is used in the engines of the Hyper-Speeders, which are boat-like craft designed to cross Remie x 3's vast ocean, the Globe's Sea. The RISF Ultimate also uses it for gravity, as it would be hard to create it with spinning when the ship is over a light-year in diameter.

This element is one of the many references to the number 137 in the Remie Universe, suggesting the number may be an important part of the future. Also, since Remenium has such a high Atomic Number, it cannot be created inside of stars, meaning that the deposit of this mysterious element must either be artificial in origin or it is made in an extraordinarily powerful explosion.

Thanks to how hard it is to mine, Remenium is a fairly expensive object to have, though not as much as liquid Hydrogen, the fuel for most Fusion based engines, making it an economical option for propelling craft.
