Novium

Novium is a material that is very rare in the universe. It is required to construct a distortion drive, but a very small amount is needed (less than a milligram).

Novium is used in drive cores because of its unique properties, it somehow multiples electrical energy that is fed into it (which, according to the laws of physics, shouldn't be possible). This power is used to drive the field projectors ships use to manipulate spacetime.
