[Short Story] Icathia origins story

Before the rise of Demacia and Noxus. Before the Runic Wars. Even before the fall of the great empire of Shurima… Existed a city named Icathia. The city’s inhabitants lived in prosperity, using the Runic Stones as an energy source, a different type of runes when compared to the World Runes mentioned by Ryze. Said Runic Stones were an incredible source of energy, believed to be infinite by many of the citizen of the city. Those magical stones prompted the city to evolve quickly, becoming the pioneer in many technological advances that are still considered to be futuristic even for Piltover right now. What was not taken into consideration, however, is the ability of the stones to amplify feelings and give them form. And when the city started getting gnawed from the inside by hate, greed, pride, lust, and other negative feelings that abominations started to appear along the streets of the futuristic city. Creatures of darkness that attempted to consume anything that still had the touch of light in it, from humans to animals, nothing was left aside. They were some of the victims that had transformed into something quite…Unique, as their minds were as abnormal as it can get. One of those people was Velstruch Kozm, a man with inexhaustible thirst for more knowledge. Some of the monsters also merged together creating gigantic amalgamations. Hopefully enough, the Runic Stones also gave birth to creatures to noble heroes, bathing in light. Some of them took the form of angels, some gained inhuman strength, speed, and multiple other abilities. The fight to seal the creatures of darkness was long and devastating for the heroes of light, who lost some of their best individuals in the process. But in a final push that was assisted by the newly made Shurima, the darkness was pushed back in a crack between realities, when they are said to still be residing. But now… The now pulsating seal weakens, and what was once human shall consume the world again, if it is not for the one chosen by the Legendary Blade, the last remnant of the most powerful of all the Lightbringers.

I'll be extending this story with time and polishing it little by little, I just wanted to share this beginning with you guys to get your input on the story's connections and on the writing (I really need to train on that).
