Superluminal

Traveling faster than the speed of light. This is not directly possible normally by Special Relativity, so, in Solar Storms, humanity and others cheat through various means.

Tachyons were the first method so discovered by humans, enabling faster-than-light communications over vast distances. This is immensely energy intensive, but works outside and independent of halons, and is easier to secure, so it is still used. Without the aid of a Klein tap or an immense amount of patterns, projectors require a significant fraction of a star's output to be viable.

Stargates were the second method engineered by humans. These use immense amounts of energy to warp a region of space between two stars, such that a distance in light-years is reduced to that of several millimeters. Humans built a few dozen such pairs before the Purge, and the eight gates that once linked to Sol are now known as the Dreadskearns. The Triad use those gates constructed by other races - human or otherwise, though the Procyon Concord, the renlai and mankind continue to build more.

Hyperspace conduits can stretch out into one or more of several dimensions, creating a complex maze of sorts that crisscrosses over the surface of the Universe. These are actually artificially constructed - originally by the Renlai, and later expanded upon by the Soronen. Humans and primii often add new links to the network, or strategically alter current ones. Using current networks takes little technology, though moving through hyperspace has many odd effects. Hyperspace nodes must be anchored in a halon, near a large stellar mass.
