I've read over the bit on the Webway in The Soul Reaver and then, loving what I saw there, I even picked up the Dark Eldar Codex. However, the bits on the Webway left me wondering about a few things.
1) Is there atmosphere within the Webway? I know that the larger arterials are big enough for spacecraft, but I also know that we have all sorts of fliers in Commorragh, so I'm curious. Is it like a 'tubular planet' with atmosphere around the insides of the lumen (where the cities are based) but vacuum in the center (where the spires reach toward)?
2) Are there natural points of access to the Webway, or are they all constructs?
3) Is it possible to mount a Webway portal in a starship? Would this be a reasonable xenos component?
4) Is it reasonable to have something like a Wraithgate (a man-portable Webway portal that can be used to move individuals and even small vehicles), and what would be the Availability?
5) Can the Webway be accessed from the Warp? Would a Gellar Field interfere with using a Wraithgate (assuming that the Wraithgate was aboard the ship with the field up)?
