The End of Purgatory

[Welcome to Purgatory]
A never ending game with limitless choices but a limited ending, a game that always ended the same way, in ruins. No matter what choice you made it was always destruction and solitude up till the very end. Yet even with such an end there was one person, one player that never stopped. He played, played, and played up till the end hundreds of times hoping to change the ending of the character he held dear, Aureus. He wanted to change his end so much he forgot about his own ending, So, even till the end of his own life he kept the same will.
"I could've done it. I could've saved him..I could've properly ended this crappy story!" He cried at the very end of his own life.
[Prove those words true]
As if responding to his pleas he was given a chance, a chance to change the fate of not only Aureus. but the world of Purgatory itself.
[Do what I couldn't do. Finish this game the way you want. Reach the end you've been longing for, the End of Purgatory as you will it]
