The balance of the Mirror Worlds by Aillin

It was a bloodier and more serious battle than ever before, during which Moira got bored with her game and started a new one with some help. Darksea the King of Darkness sacrificed himself so that the other members of the Forger of Darkness could escape. End the God of Destruction, was the only one who stubborn refused to leave; he fought alongside Darksea to the very end, in the hope that both of them would be able to leave alive... Some time has passed since then, Fantasy the creator and Lightfire the Guardian of the Light, got together and had a child Indigo Ray. They did not known that Indigo is none other than the reborn Darksea with all of his memories, who cursed Moira. 

End the God of Destruction, follows him back to the life born as the child of the God of Death and a blood mage, refusing to let go of his Star. 

 We follow Indigo life and fight for the balance, as he met many who could stand by his side in the fight against Moira. When your past define you as much as your present. Who is Indigo in the end? How everyone while react when the true will be reviled? How many will accept his blood past and stay by his side despite everything?

Warning: Bloody and cruel pasts, physical abuse, self-harm, emotionally difficult scenes, the burden of expectations, fighting, blood, wounds and mention of death.

The original idea can be found under the title "Reborn" in A_Bored_Reader's post, "Undertale ideas for stories that hit me like a brick." Which I asked permission to use before I wrote the Undertale fan fiction in English and Hungarian titled Reborn of balance. Those interested can read the original version, which I later rewrote as The balance of the Mirror Worlds, adapting it to my own setting for publication. This is a little taste to see how interested others are in the story that will contain the first 4 chapters.

Prologue

Filling the planets with life was the task of the shapers of the worlds and the creators. There weren't many of them, so one creator was responsible for more planetary systems, creating thousands of worlds in the process. And Fantasy was one of those creators who was deeply attached to the world's they created and stayed with it on their path of development. Therefore, the appearance of the destroyer, who wiped out entire worlds and planets, affected Fantasy quite badly, who fought to protect the worlds. 

Consequently, two teams eventually emerged the "Guardians of the Worlds" and the "Forger of Darkness" with both the God of Destruction and the Creator playing roles in their formation. From the very beginning, Moira the thread mover, paid a lot of attention to the Mirror galaxy created by Fantasy. As an otherworldly entity they figure hovered on the edge of existence. By moving the threads Moira turned this world into a playground. Watching the centuries-old fight Moira got bored of their own game in the middle of a fight and decided to start a new one, whit some help. 

The members of the Forger of darkness sensed that something was wrong when the open minded Azure didn't join the fight. This battle was bloodier and more serious than ever and, the Forger of darkness were losing it. The leader of the group Darksea the king of darkness sacrificed himself so the rest of the gang could escape. End the God of destruction was the only one, who stubbornly refused and fight beside him to the very end, in the hope that they both would be able to leave alive. Fantasy and Lightfire didn't even really remember, how they managed to win. They only saw as their enemies with a recognition in their eyes, looked one last time into each other's eyes before they became dust. There was nothing in the way of the Mirror galaxy worlds now, most celebrated and felt relieved. 

The survivors of the Forger of darkness have not been heard of ever since. Now that the threat was gone, they can finally be happy, or so they though. Moira watched as result of taking Darksea and End's life, the multiverse started to slowly die due to the imbalance. Moira had no intention of letting the world die, 'they' just wanted to see them fight desperately for survival. And they already knew, how they could make this really fun.
