Death (personification): Death, also known as the Grim Reaper, is frequently imagined as a personified force, due to its prominent place in human culture.  In some mythologies, the Grim Reaper causes the victim's death by coming to collect them.  In turn, people in some stories try to hold on to life by avoiding Death's visit, or by fending Death off with bribery or tricks.  Other beliefs hold that the Spectre of Death is only a psychopomp, serving to sever the last ties between the soul and the body, and to guide the deceased to the afterlife, without having any control over when or how the victim dies.  Death is most often personified in male form, although in certain cultures Death is perceived as female (for instance, Marzanna in Slavic mythology).
