Fo Engines

Fo engines work with the element Flobeum and small amounts of dark energy in order to propulse faster then the speed of light. The engines are able to dialate time around the ship in order to move faster then the speed of light. Though this enables a ship to move from one solar system to the next with ease, it would take the ship years to arrive at the next system. This is why the Alliance and other species use the phase gates.
