Earth was once the cradle of humanity. Before the Orokin ruled, its towers reached the heavens and its cities lit the night brighter than the stars. Those ages were long gone by the time the Orokin returned to reclaim the Sol System after the Old War, but what they found was not an empty shell. The last of humankind was still there, holding on in the ruins of its ancestral world.
Among them was a shy, tired boy named Colt. He wandered the broken monuments around his grandparents' home and found small moments of joy among the relics of a civilization that had once touched the sky. The Orokin's arrival turned discovery into reclamation, and their colony spread across Earth's wounded soil. The Ostrons, born of mingled human and Grineer stock, became Earth's new settlers. Colt stayed different. He was a pure-blooded human, an anomaly in a System that had long forgotten what that meant.
His fate was sealed when he was chosen for Orokin training. He was taken from Earth to the Sol Academy of Phobos, where the halls of Zenurik schooled him in diplomacy, statecraft, and the quieter arts of war. Later, aboard the Zariman Ten Zero, his mother worked as a healer while Colt buried himself in forbidden studies: Eternalism, the philosophies of Lua, and the mechanist theories of Albrecht Entrati. He was just as fascinated by Orokin tortures like the Jade Light as by their great instruments of salvation, the Warframes.
Then came the Void jump, and like the other children, Colt was changed. The boy who had studied Warframes from a distance was now bound to them, and he wielded their power as if he had been born to it.
His path turned during the second Orokin expedition to Earth, sent to find out why a Warframe had vanished. In the groves of Sylvanus, Colt found her: Titania. She was more than a machine or a tool. She was a spirit of the forest, a dream given form. Titania called to him, and Colt gave himself to her Continuity without a second thought. From then on, child and Warframe were one soul.
Centuries passed. When the Tenno rose against their masters, Colt stood out as a tactician without equal rather than just another soldier. In the Solar Rail wars his strategies and his command of necramechs reshaped battlefields and won territories and rails for the Grand Order. His brilliance lifted his allies and his fellow knights to prominence, and it also exposed how corrupt the Grand Master he served had become.
Disgusted by the greed and betrayal, Colt became the spark of rebellion. He led the first and only uprising against the one who shall not be named, shattered the Grand Order, and scattered what was left of it across the stars. As the System broke apart into clans and guilds, Colt gathered his most loyal allies, and out of that bond and their shared cause he built something new.
Sanctum Aeterna.
It was never meant to be an empire of vanity or an order built on control. Sanctum Aeterna was made to keep the balance between Sol and Lua, light and shadow, purpose and freedom, and so Colt gave it two orders. The Knights of Aeterna carry the sword and stand against tyranny. The Angels of Aeterna, named for the healers who tended the children of the Zariman, carry the lost home and lift up the fallen. Neither stands above the other, and every Tenno of the Sanctum belongs to both its causes.
For his vision and his strategies, Colt was given a name that is still spoken today.
Val Narmonai, the Leader of Tacticians.
