{{Quotation|title= |text=The things the Horseman represent in pestilence, famine and war are like forces of natures and are states that humans experience all the time. So it isn't as though when Lucifer comes on the scene he brings these monsters with him that are unleashed that we haven't been experiencing the effects of throughout history. It's more that he gathers them to him.|author= [[Sera Gamble]]|source= [[Supernatural: The Official Companion Season 5]]}}The Horsemen are powerful beings that act as instruments of chaos and destruction during the [[Apocalypse]]. Their actual biological origin remains unclear and has yet to be represented in Canon itself. War refers to them as his siblings; The actual ages of them compared to one another remains unknown, however, [[Death]] is the oldest Horseman, as he existed during the origin of time. Their relationship to each other is also unclear. Although [[Pestilence]] professes compassion for allegiance to [[War]] and [[Famine]].
[[War]] and [[Famine]] were both loyal to Lucifer's plans, whereas [[Death]] wasn't subjected to Lucifer's agenda until Lucifer bound Death to him through a spell, and [[Pestilence]] worked for Lucifer to which he spread the [[Croatoan virus]], but he learned that War and Famine both fell into an impaired state due to the actions of Sam and Dean which made him stray from Lucifer's plans.
