Cthulhu Ran Out of the Small Garden

I once thought that the pets I kept in my box garden were just some rather strange little pets. I feed the stars, and they respond with the evolution of civilization. It wasn't until the global sky shattered, and my "pets" stretched out their tentacles, turning the city into a twisted altar - that I realized that what I had raised for eight years was a sleeping god. The world fell into madness, and the army collapsed before indescribable power. And I can hear their whispers of destruction mixed with their affection for me, the "keeper." But that's not where the truth ends. A more ancient and huge will is staring at me through the broken dimension. It made me understand that I am not the Creator, but just a caretaker who opens the cage for them. Now, they want me to make a choice: as a final sacrifice to witness the end of the old world; or as a guide to crown the coming of the new god. My answer will determine whether the two universes will return to deathly silence or fall into eternal night.
