Description: SCP:5992 is a horses' spirit, that when put in danger, can possess other horses and is seemingly immortal
SCP-5992 was born from a mythic horse known as Arion, an immortal god horse (supposedly) in Greek Mythology. For generations, *he* stayed doing activities horses normally do to live. Grazing, eating, riding, until he was adopted by a mercenary on the greek islet of Kefalonia. He stayed with this mercenary until he died, shortly thereafter boarding a merchant ship to Egypt, and then through the Suez canal, making many stops in many different landmarks along the way. One instance, however, stated that a horse matching the physical description of this horse in about was trying to be captured by a group of bandits in Poompuhar Port, supposedly massacred them in self-defense, and then sailed on a different ship for about 100 years across the Bay of Bengal, to South China sea, all the way to Korea in what is now the port city of Busan. However, there was a storm knocking the ship off course, wrecking it on Komoda Beach, in the Japanese islet of Tsushima, in around 1200 A.C.E. There, SCP-5992 lived for about 70 years until the Mongol invasion of Japan struck Tsushima island. There he was slaughtered by Mongol warriors and had discovered his unique power to possess other horses when in danger. Then, he used his possess a horse in what is now southern Belgium and served as an exotic stable for Austrian dignitary. SCP-5992 has stayed in Belgium to this day and some have rumored him to be a horse in a barn, with a collar on his neck that reads: "Fabio"
