The Webway Gate, also known as the Webway Nexus or Webway Gate, is a series of technological artifacts composed of Wraithbone that are incorporated into the hull of Craftworlds and provide a link into the Webway. Webway Nexuses are also found scattered on worlds throughout the Galaxy, allowing the Eldar to travel to many planets.
Webway Gates are found on both Eldar Craftworlds and throughout worlds of the galaxy. When not in use, the Gates are dormant and are hidden to the lesser races.
Among the greatest of these belongs to Alurmen, whose Nexus was unmatched by the other Craftworlds. Through its Nexus, the inhabitants of Alurmen could send explorers and traders with an ease that was second only to the Old Ones. Its Nexus of Webway Gates allowed it to be connected to other Craftworlds, Exodite colonies, Maiden Worlds, and other ancient Eldar sites making it Craftworld Alurmen's greatest strength as well as treasure.[1a]
Around four thousand years ago, during the Age of Apostasy, Ahriman learned of the Nexus and intended to use it to travel to the fabled Black Library of Chaos. Learning of this future, the Farseers of Alurmen decided to hide their Craftworld in order to protect the Webway Nexus as they knew they could not fight the Sorceror.[1a] In desperation, they severed ties with the other Eldar and sent Alurmen into the Cerberus Shroud where they activated ancient C'tan devices designed to suppress the power of the Warp thus hiding them from Ahriman's mystical sight but at the cost of being damned by the rest of their race for using Yngir technology.[1b]
