The Reserves. The reserve corps of administrator seraphim on Jerusem spend much of their waiting time in visiting, as spirit companions, with the newly arrived ascending mortals from the various worlds of the system—the accredited graduates of the mansion worlds. One of the delights of your sojourn on Jerusem will be to talk and visit, during recess periods, with these much-traveled and many-experienced seraphim of the waiting reserve corps.
