In the folk tradition it is anathema to bury the dead, as this is seen as an attempt to hide what is rightfully Death's within the earth. Instead, the dead are taken to large cylindrical towers.
New bodies are placed on top of the tower, where they are picked clean by buzzards. The top of the tower is a loose grating, and as the bodies disarticulate the bones fall through into the tower's interior.
The bones fall into a central well, which is full of rainwater. Members of the Ecclesiarchy take the finger bones and arrange them on special shelves (fingers being that which separates man from beast), and tend the central well to ensure that the bones properly disintegrate. Water from the well is holy, and is used to consecrate growing fields.
