Elder Titan Fixes Equestria

Our story begins with the Titans. These were an ancient race formed out of the early days of the universe, when the expanding energies and spacetime were yet to be confounded by the passage of aeons. Specifically, we will follow one of their great innovators, one whose name was forsaken long ago so that he may better serve his people: Elder Titan.

As with all protagonists, he has a major part in our story. In fact, it wouldn't exist without his mistake. Yes, mistake. He remembers only vaguely his wrongdoing.

There he was, at the Forge of Creation. Ah, the Forge... it is not an object alone; it has copies, different versions of itself across all planes of creation. Which means that, yes, it existed in the past, in the future, and also in the present. It was everywhere in space, and yet somehow could be approached only through the path of the Titans. Hewn of the earliest rock and imbued with the proto-energies of the universe, this Forge's power to create was deeply revered by all. And Elder Titan? He was the Master Shaper of his people, the only one permitted to lay his hands on it. It was the greatest honor one could be bestowed with.

The title of Master Shaper meant one thing first and foremost: that he alone, among all that lived and breathed in the vastness of the cosmos, was allowed to tamper with the fundamental forces and fine-tuned truths of reality. He alone was allowed to hew concepts out of nothingness. Time, light, entropy, the very nature of space... all could be altered, so long as the change could be conceived in thought. And once the hammer was raised and pounded on the anvil, the changes would take form, for the Master Shapers are the innovators of the Titan race, creating realities and dimensions in the same way peoples of this time invent machines, or craft weapons, or discover technologies.

Elder Titan had a particular liking for the physical universe. It was a nexus, a place of experimentation and diversity. Perhaps it was only this very specific interest that saved all realities from what would come next. Being a Master Shaper was his great power... and his great undoing.

  At the very moment he raised the hammer, into his mind came an insidious thought -- a thought of the physical universe allowed to run itself, wherein the fundamental forces ran amok, settling among themselves the disputes of reality. He only realized the true potential of this thought once his strike had landed on the anvil. Immediately, the physical reality he knew changed. No longer bound by the tight regulations of Master Shapers past, the fundamental forces revealed their unbridled power. Rifts too many and too diverse in nature to control began springing up everywhere. A mad lightshow of the energies and forces of creation displayed before his eyes. Time was twisted, reality warped. Chaos enveloped him, and he knew he had done something of horrible consequence to one of the most important planes hewn of Titan toil. He had handed over its fate to forces that could not think beyond their own scope, that could not comprehend anything other than themselves. The other Titans, they would be fine. Living amongst themselves in a specially designed dimension ruled by its own laws and forces, they would see the shaken physical universe as we would see a distant fire. Except that this fire marked the destruction of their greatest experiment. One that could never be repaired, only tossed aside.

In that maelstrom, nothing made sense. In a second, aeons could pass, and every step could deliver one to the very edges of known creation. In his stumbling, he fell. The manifestation of the Forge shattered, and the path of Titans crumbled beneath him. Into the largest rift he fell. He knew not where he would be dispensed, or when; only that what he would see next would be a horrifying version of creation -- one he had created.
