in world revoked cosmology, the planet earth has a big ball of meat at its center. this flesh core is what allows clays to reproduce by putting their corpses and giblets into the ground and what facilitates memory transference through the earth heart/locus/core organ, which is a special ball of clay/dirt/sand/etc. kept in their chest cavity that preserves clay resurrection and reproduction. clays can die, but as long as their locus is intact they can be planted and grow a new clay who's the same person. however, if the earth heart is damaged or shattered, upon replanting you will get multiple clays or a brand new clay.
