Outcasts in Vanilla have rumours stating the respect for Nomads as Klaw stated above, and their graveyard, which is "protected" by the Spirits.
More of an animistic relationship than an organised religion. Worship comes in different forms, after all. It is not always about prostrating yourself on your belly before an almighty presence that shaped the very cosmos to be his plaything.
I do not have access to said rumours at this present time, because I am travelling and working, so I posted the above "Sure. Sure." to throw an oar at chopper's incorrect and biased accusations. It would be tragic if people went along with his.. theory.
