Gridwalkers
Gridwalkers are Puzzlebox inhabitants, usually of Downwarp, that hold to a particular set of holistic animist beliefs. Puzzlebox faction catalogs sometimes refer to active and visible Gridwalkers as a faction called the "Gridshamans," but it's hard to find actual evidence of large-scale faction-like organization, or the use of that term by Gridwalkers themselves, though their belief system does have many features in common with shamanism (including work with spirits, altered states, and sometimes even an initiatory 'death'). Instead, Gridwalkers simply say that they have a particular way of looking at and interacting with the world.
Worldview
To the Gridwalkers, all of creation, whether it be material, conceptual, or somehow something else entirely, is part of an infinitely complex living system called the Grid.
