The followers of the mechanogod Whrrrm, those who could never have come about until the advent of steamtech.

~The True History of the Order, by F’ian circa 300 AW
A certain tribe in a valley believes that the soul remains trapped in the body after death and is aware of it. So they treat their dead as if they are alive, talking to them and keeping them at home. They are used to the stink and for some reason are also immune to the diseases that this practise causes but outsiders are not so lucky.
