Artifacts are still pandora's box so to speak, hence still called artifacts, and possibly quite dangerous. Makes sense for Houses still having ban on them. One such artifact case (those brown things are cases for those who don't know, it's in recreated real-time cutscene intro that was supposed to tie along with cutscene of FP7 destruction) held the purple "key" to realign Dyson Sphere energy grid.
As for the Nomads themselves I took the path for the Keepers that precedes even that document, using conceptual artwork instead where they had different physical form.
Artifact case for those wondering where did hypergate key came from.
' Wrote:well, nomads arent suposed to be there either anymore, eh?
And what on earth made you think so, eh? Re-read last paragraph in the second document. No, re-read it again. And again. For as many times as it takes you to actually read it. Nomads are here to stay and aren't in haste to go elsewhere. Period.
