Dwarves a websource states that they left in the 20s. But since the Underground didn't exist till AFTER THE NIGHT OF RAGE (2039), this is obviously wrong. If you can find sourcebooks/novels with details, please clarify; for now I am sticking with the 40s... --UserPiotrus 1311, 17 November 2008 (EST)
You are right - I didn't put the "20" in the article. - It was just there, as I did the link to our German partner-wiki.

So, sources. SS is clear on the early 20s for the dwarf exodus. NS is even worse, discussing the Night of Rage ''before'' mentioning the schism of the 2020s, but also clearly indicating that the dwarves and orks came here in en masse after NoR (2039), then the dwarves were expelled in the 2020s. RH doesn't say much on this, although it indicates the orks came here after NoR. So, I think it's pretty clear somebody made an error that was repeated until the 3rd edition. Nothing in 4th or 5th clarifies this; I think it's best to treat 2020s as an error and just drop it; it was meant to be probably 2040s. --UserPiotrus (User talkPiotrus) 1337, February 1, 2014 (UTC)

I am not adding locations listed at http//www.amurgsval.org/shadowrun/OrkUnderground.html, http//sr4orkunderground.wikispaces.com/My+World, as far as I can tell they are all non-canon. They could be described in separate articles tagged non-canon, but I don't have time to work on this stuff, when there's so much canon stuff to add. --UserPiotrus (User talkPiotrus) 1337, February 1, 2014 (UTC)
See TalkOrk Underground for my comment on when the dwarves left.--UserPiotrus 1312, 17 November 2008 (EST)
