off the top of my head:
unlike stargates, which make wormholes each time they are activated, the webway is always there, but the stucture is not fixed in a way we can understand, only Harlqins and the Guardins of the black library know how it works and have maps of it.
the portals can be open and closed at a varying amout at the whim of a farseer, but only as large as the webgate can support, a portal can be closed forever but the conection to the webway will still be there but it would just be a dead end,
? ? ?from what i can rember the Old One's made the webway and the Black Libary for the Eldar because it was so dangrous for them to travel in the warp for long periods, even with the Old One tec they would go mad, die or be possessed by a Daemon.
? ? ?and i think i've read someware the the Black Libary is all the Old One's Knowlage, so there should be the information on how to make more bits of webway. plus there's alot of stuff the Eldar added over the countless Millenna and it's also ment to be able to record alot of stuff for it's self but don't ask me how i know this or were all this into comes from
?
dark reses of the mind and all that.hope that helps.
p.s. i think i've been playing Eldar for to long, it seams i know this stuff to well, need to get a life!!!!!!!!!!!!!!
Go figure.
