The Javelin Drive is an FTL method used exclusively by the Aeno Coalition. Derived from the propulsion method used by the notorious Javelins, It uses an exponential thrust curve to accelerate beyond the speed of light. Once beyond the lightspeed barrier, acceleration speeds up dramatically as the craft goes ultrafrictionless. To explain this, let's get two arrows. 1 arrow is fired in space, and 1 on a planet with an atmosphere. The arrow fired in atmosphere goes a few hundred feet, but friction from air slows it down, and it lands in the ground. The arrow fired in space, however, keeps on going forever, since there is no air molecules to slow it down. Now a spacecraft traveling sublight is subjected to invisible forces, like the arrow in atmosphere. But once a craft goes FTL, it turns from an in-atmo arrow to one in space. If it is under acceleration, it can accelerate hundreds of times faster. Hard concept to grasp.
Once the First Aeno-Vasden War had ended, the scientists on Kor, after a few years, applied it to regular spacecraft. The gateway system was obsolete. Any ship equipped with a Javelin Drive could go, anywhere. However, there is one drawback: Javelin Drives are significantly slower than other methods of FTL, like Warp Drives, Hyperlanes, or Wormholes.
