Mythical File - The Four Horsemen of the Apocalypse
The Four Horsemen are generally normal people out in the world. It's rare that they require the services of the FIA teams, though when they do, they have the choice between Haas or Sauber/Audi. Death prefers Haas while War prefers Sauber/Audi and Famine and Pestilence have no real preference, generally.
Death actually gets her strength from the grief of the living, rather than actually having any motivation to cause harm. Because of this, she runs a relatively small, but successful chain of funeral home businesses. Currently she resides in Florida and regularly attends the Miami GP.
War's power comes more from dissent and anger than full blown war conflict. He works as an on site journalist or reporter and has garnered a reputation for being the best reporter on scene for rallies, protests, and riots. He has also done several reports from active war zones, though he prefers the smaller conflicts unless he is need of a large amount of power for something.
Famine's major focus is on scarcity and they've been well fed with the growing class divide. While food is still a major source of this scarcity, it can also be fueled by a lack of money, jobs, housing, and other basic needs. Famine is employed as a chef at a Michelin star restaurant, but they volunteer at soup kitchens and shelters frequently.
Pestilence is powered by generally poor health. While he works at a disease research facility, the majority of his well being is fueled by the generally poor mental health of the world. He has refused to answer all questions about if he was involved with the outbreak of Covid, and is continuing his silence for the most recently discovered new strain of influenza.
Each Horseman keeps their horse close by, generally in a sort of pocket dimension, powered by their 'specialty,' though Death keeps his on a large farm property he owns. All the Horsemen turn to Ferrari for assistance if anything is necessary for their horse's health. This mainly entails regular re-shoeing, but has occasionally been for other minor troubles.
Though the Horsemen are immortal, they require regular reincarnation, since their bodies do age. They do have control over this, however. Usually this means that when one of them is ready for a new life, they find a family with a child that is around the age of 6 or 7. After several days of magically assisted recon, the Horseman will then take over the child's life. The child's 'soul' or existence is more or less enveloped by the Horsemen, who then retains all the child's memories. While many of the people informed about this are ill at ease about the process, there is nothing yet discovered to change or aid this, though intense research is being done by genetic facilities to determine the possible use of cloning to provide a physical form for these transitions.
