Once upon a time, in a land far far away, there were two neighboring kingdoms who were meant to be wed. The kingdom named Medu was ruled by a prince named Cocalo and the next door kingdom Oomza was governed by a princess named Localo. The queens and kings of these nations had children around the same time and while they already had plans to join forces they decided to give their babies similar names as an agreement to unite the lands.
Cocalo and Localo grew up together as if siblings although their parents married them before either of them turned one year old. Everything was going well, with the dominions being one they were more powerful and prospered. They grew up healthy and lusty. Cocalo was tall and build near godliness. He was skinny but by no means scrawny, although he wasn't the strongest man in the kingdom he was the one who held the most magical potential.
Localo on the other hand was short and sturdy, being only 5ft 1in and weighing 110 pounds. Despite her compacted stature she could put most fighters to shame if they were to challenge her in a duel. The prince and princess were the pride of the kingdom and they were well loved by their beloved subjects.
It started small, tiny rips in the fabric of space began to appear around the empire. When people looked into these cracks they saw a dark and desolate place filled with unimaginable monsters and a hazy purple glow. As time went on the tears grew larger in size until a man with purple cloth that covered his face and torso stepped out of the crack and floated across the lands towards the main castle. Many of the soldiers and citizens tried to stop this strange magical man from entering the castle but all failed. What the citizens now call Zams followed this muscular man around. Cocalo felt this dark magic and challenged this prophet to a magic duel. He believed he could stop him from hurting any more of his citizens. He sent out white wisps to attack this man whose purple static magic seemed to damage anything it touches. Despite the prince's best efforts even his magic was no match for Malzahar.
Cocalo lay on the ground in pain as the Zams scratched at him and their master seemed to be invading his mind with flashes of dark futures in a land he had never heard before. The princess who was being held back by her parents broke free and rushed to the prince's side. Anger filled her mind and she lunged at the Prophet of the Void. No matter how strong she was, she was unable to break through the purple shield that surrounded him. He grabbed Localo by her collar and infused her with his tainted magic. Her cute appearance began to shift, her teeth became sharp and her hands grew claws similar to those nightmare creatures within the darkness of the cracks. Her skin paled and small horns began to grow from her temples.
"You will bring the destruction of runeterra" the prophet said.
"NO!" Cocalo casted a shield around his Localo which caused the Prophet to drop her. He rushed to her side even though he was profusely bleeding from the Zams. The Zams dragged Localo into the void and the Prophet followed. The tears closed up and they were gone leaving Cocalo devistated. Never had they had been separated as they were now. Just as he believed all hope to follow was gone, yet another strange magic user flashed into existence. He too had the feeling of dark magic but something was different about him. He looked more menacing than the prophet but he said he would reunite them. Localo who was meant to destroy the world and Cocalo who was meant to end her and save it.
Some say the voidwalker was able to reunite them but are stuck in another world and a different time. The prince Cocalo would protect princess Localo no matter what but if she is to end the world would he be able to stop her or would he continue to protect her even if it means watching the world fall apart.
