Faction: Neo-Titanomachy
Titans are, at this point, a long-standing tradition. But of course, such things had to start somewhere. Someone had to come up with every idea. For the idea of Titans, and Titan duels, the idea can be easily traced back to the Titanomachy. The old Titanomachy that is. Under the leadership of a man known only as Helios, the Titanomachy created the first model of Titan. With the power of these immense machines, they dominated planetary warfare when humanity was still barely past its own neighborhood. It was with this power that they brought the tradition of Titan Dueling to the rest of humanity. The old Titanomachy where strict adherents to tradition, especially when it came to Titan Duels, which was effectively their entire culture. Thus, for a long time, Titans rarely ever changed.
It was this traditionalism that would prove to be the original Titanomachy's downfall. With time, they lost the power that allowed them to so strictly regulate Titans, and thus, found their foes improving around them while they refused to let go of the old ways, the old designs, the old titans. And indeed, the fall of Helios is not a martyr's tale. In a final stand against those who would dethrone the Titanomachy, he declared a duel against the then leader of the United Earth Collective. Helios marched to battle in his own personal Titan, the very first one ever designed, both it and his skill maintained and honed over decades of combat... and he was crushed. The duel saw its end within seconds as Helios was obliterated by a shot from the much more advanced enemy titans arm cannons.
That was the end for the Titanomachy, their leader and founder was dead, their ways had been proven inferior, once and for all, and they had been stripped of all power. The Titanomachy disbanded, and humanity moved on. But while the Titanomachy was gone, its people, the Olympians, those who had settled on Titan itself, never lost that obsession with the duels, nor their spark for engineering. Their people filled the void of Titan Combat with personal Mech duels. With time, the world around them has gotten fat, greedy, and complacent, and a new Olympian, going only by the title of Prometheus, has risen to power through Mech combat. Consolidating their people and resources into one nation once again, it is time for the Neo-Titanomachy to rise from the ashes of the old.
