Examples of this practice may be viewed in Hell 71, and in the lower levels of the White-Eyed Woman

On the Creation of Hollows : Commentary by Payapop Pritram
"The practice still persists among devilkind in a more degenerate form, with the creation of ‘hollows’. Well-connected devils will go to great lengths to kidnap human chattel, which are ritualistically ‘hollowed’ out, personality and face alike, their life force preserve through arcane means until the devil may possess them at its leisure, without any inconvenience."
