Gridwalkers
The word 'Gridshaman' is one of those used for the easiest-to-find spiritual tradition in Downwarp. Outsiders usually see Gridshamans as a faction, but few on Downwarp seem to see it that way, nor even use the word; the more spiritual folks in warp call themselves 'Gridwalkers' or 'Gridworkers' instead. That being said, the tradition does involve an animist worldview, and work with the spirits and altered states, and even a sort of initiatory death, so the 'shamanism' label is an understandable and reasonable one to use.
