Hyperspace was an alternate dimension whose entry was required by the use of mist. Hyperspace could be use to travel faster than light speeds. Hyperspace routes were lanes that were trafficked by vehicles. Hyperlanes did not actually have a boundary but were places safe for travel, specifically paths that avoided gravity wells. Hyperspace is sometimes called the world of the Mist by primitive cultures who have somehow discovered it. Entire known area of Hyperspace is composed of Mist.
