Galatian and some Leng’gui propulsion systems allow FTL travel using an advanced piece of technology known as the ILAD core or Interdimensional Luminal Aetherite Drive. Its power source is based on an exotic energy found in naturally occurring aetherite deposits – a rare mineral that is rich in dark matter condensates. This drive is not exactly a form of propulsion on its own; rather, it is a quantum tunneller coupled with an interdimensional quantum mapping system. Together, these tools allow the appearance of faster-than-light travel via the creation of localized wormholes in which space is folded and stretched. In truth, the vessel itself travels at subluminal speeds through the tunnels, always arriving near instantly on the other side of the wormhole once the tunnel path is established.
This technology is, in miniature, what the gate system is for most interstellar travel throughout the kingdoms. However, because of its smaller size, its range is limited, as is the number of destinations that it supports. In the Galatian network, specific destinations and drive systems with more advanced protocols, which enable further travel or interdimensional hopping, are code-locked due to the encryption of these functions for the safety of uninitiated systems and species. These code locks are typically called GAK or Galatian Aether Keys. They must be used to enable the functionality or to override the safety protocols of such systems.
