Ra Endymion - History: Ra Endymion was born on Terra during the Unification Wars to Koja Zu, the Minister of the Anuatan Steppes, around the time of the Battle of Maulland Sen. Ra's mother was executed by Captain-General Constantin Valdor for the high crime of stealing Terra's last remaining ocean when Ra was only four standard years old. He was taken after her death by the Legio Custodes as a potential candidate to join their ranks.The young boy received the name "Ra" in honour of the ancient Gyptian sun god and eventually rose to become the leader of Squad Dynastes, later dubbed the Lords of Terra by the Emperor Himself. This squad of the Custodians was composed of twenty sons and nephews who had been taken as tributes from various defeated Terran rulers and techno-barbarian warlords. By the opening years of the galaxy-wide conflict known as the Horus Heresy, Ra had earned eight-hundred and seventy-one personal names in honour of valorous deeds and was raised to the exalted rank of Custodian Tribune within the Legio Custodes.Following the Crimson King's folly, when Magnus the Red attempted to warn the Emperor through sorcerous means of Horus' corruption and eventual perfidy, the wards placed on the Imperial extension of the Webway deep within the Imperial Palace's dungeons were breached, which allowed thedaemonic legions of Chaos to encroach upon the Emperor's Palace. Five Terran years into the war, things began to go badly for the Imperial forces, as the never-ending mortal and daemonic legions of Chaos threatened to breach the sanctity of the Palace's dungeons.With the deaths of both Tribunes Kadai Vilaccan and Jasac, Ra Endymion was given sole command over the Custodians fighting the so-called "War Within the Webway." When the derelict Aeldari city within the Webway known as Calastar (nicknamed the "Impossible City" by the Imperials) fell to the Daemonic hordes' assault, the Emperor was finally able to leave the Golden Throne, following the sacrifice of one-thousand psykers in what became known as the "Unspoken Sanction," in order to cover the retreat of the crippled Imperial forces and to confront the Daemon Drach'nyen.In a final confrontation, the Daemon took the form of a Stone Age war-chief, the first Human to have taken another Human's life, and the Neverborn impaled the Emperor, claiming that it would be His death. But the Emperor tore the Daemon, now in the form of a great Daemonic sword, from His body and with armour-boosted strength and powerful telekinetic force, hurled it from His grip at Ra. The sword impaled the Custodian Tribune, causing the Daemon to be bound within him. The Tribune didn't demand any explanation or apology. Ra was born to serve, raised to obey and chosen for the greatest illumination preceding the darkest duty.The sword quickly disappeared, for it was now bound within the Custodian's body, caged within Ra's flesh. The Daemon within him could not be killed, not even by the Emperor Himself, only imprisoned. As the last remaining Imperial forces retreated from the Imperial Webway, the Emperor ordered Ra to run deep within the myriad tunnels of the Labyrinth Dimension as far as possible, separating the Daemon from his master, which meant another day that the Imperium would stand unbroken. Ra fled deep into the Webway at his master's command, never to be seen again, his ultimate fate unknown.
