To become a channeler, one must go through a special ritual called "Yorim", which includes the placement of a long nail passing through the temporal bones of the skull, then, a vertical incision has to be made to the abdomen, letting the intestines come out to carefully place them at either end of the nail, ending the process. This ritual makes the channeler able to glimpse deeper truths into the flesh of cursed vessels inside her womb, assuming she survives the procedure.
