The Webway is a device that features in Warhammer 40,000.
The Webway was a labyrinth dimension that was part of both the Warp and realspace but was not part of either. (Codex: Eldar (4th Edition))
There were a number of variations of the Webway technology which included:
- Webway Portals : these are mobile deployable gateways that are deployed on the field and allow access to the Webway and are used by the Dark Eldar. (Codex: Dark Eldar (3rd Edition))
- Wraithgate : similar to the Webway Portals, these are deployable gates that allow reinforcements to arrive on the field through the Webway and are used by the elite strike forces of Craftworld Ulthwe Eldar.
