Devil's Palm

Devil's Palms (悪魔の手のひら), as featured in Steel Ball Run, house and/or emerge around each of the Saint Corpse Parts, in each of the locations Jesus gave on a map of North America to.

Summary
When Jesus died on the western coast of North America, a great storm and earthquake tore and reshaped the land, which divided his Corpse into 9 Parts that would be carried by animals and other forces of nature eastwards.

Carrying the Corpse Parts while migrating around the country and appearing in seemingly random places, Devil's Palms occasionally ensnare people, occasionally granting them Stands, or, still less often, a Corpse Part.

As the Boomboom Family explain, those passing through them are forever changed. Along with the Corpse Parts themselves, surviving a period in any of these locations seems to be the only way to develop a Stand. Johnny obtained his first Corpse Part from a Devil's Palm in Monument Valley, soon discovering his Stand Tusk, and Mountain Tim obtained his Stand in a similar location.

It was revealed that the Devil's Palms are sacred sites to Rock Humans.
