Millions of years ago, a beautiful snake came up with a crazy idea.
"Big Brother, I think the only way to ensure the heavens truly bleed is by taking their most prized possession. They took your mother from you, and though you claim you're fine, I know you aren't.
So why don't we take something from them?"
"That will be a suicide mission, you know that, right?"
"I know, Big Brother, but you also said one day, the happiness we so very much crave must be protected, and from my calculations, entering the Pool of Secrets is the only way.
From what I know of the Void, anything it spawns comes in one. Meaning there wouldn't be a second one out there.
If we allow the heavens to succeed, giving this heaven-defying physique, universe-shattering Body Constitution, and such terrifying techniques to their minions wouldn't be easy for us.
So we might fail, but our chances of winning are also very high.
